Germany hosted 565 international association congresses in 2025, more than any country except the United States and Italy. Yet not one German city made the global top ten. The best placed, Berlin, came twelfth worldwide with 112 congresses, according to the GlobeWatch rankings of the ICCA (International Congress and Convention Association), published in May 2026.
That gap between a strong country and the absence of one dominant city is the most useful thing an international planner can know about MICE (meetings, incentives, conferences and exhibitions) in Germany. The country does not have one obvious answer. It has a dozen credible ones, and which of them is right depends on the kind of event you are bringing.
In this guide we show you which German cities led for international congresses in 2025, why trade fair strength and congress strength are two different things, what your delegates need to get in, and how to turn the figures into a shortlist.
What makes a German city a MICE destination
A MICE destination in Germany is a city or region that actively wins meetings, incentive trips, congresses and trade fairs, usually with its own convention bureau, a congress or exhibition centre and enough hotel capacity within reach. Berlin, Munich, Hamburg, Frankfurt and Cologne are the familiar names, but the list of German cities that host international congresses every year runs to several dozen.
The general criteria behind any destination, from air access to local research clusters, are covered in our guide to what makes a MICE destination. This article applies them to one country and asks a narrower question: which German cities meet them, and how can you tell?
Picture the congress director of an international medical society. Her council wants three German candidate cities for a congress four years out, each with a reason. She has the ICCA list, a pile of bureau brochures and a vague feeling that Berlin is the default. Her real task is to show the council when the default is wrong.
Germany’s strength is breadth, not one capital
The council will like the first number. Germany ranked third in the world in 2025 with 565 international association congresses, behind the United States (792) and Italy (616), out of 12,438 association meetings that ICCA counted worldwide.
The more revealing figure is how those 565 are spread. Berlin and Munich together account for 168, just under 30 per cent. In Portugal, Lisbon alone hosted 188 of the country’s 356 congresses, more than half. In Austria, Vienna hosted 159 of 239, about two thirds (our calculation from the ICCA figures). Germany has no Lisbon and no Vienna. It has a network.

Germany as an events destination in four figures
For you as a planner, that breadth means real alternatives to the capital: cities with international experience, purpose-built venues and their own bureaus, often with better availability on your preferred dates. For German convention bureaus, it means the competition sits not only in Vienna and Copenhagen but also one motorway exit away.
The breadth goes beyond association congresses. According to the Meeting- & EventBarometer 2025/26, published in May 2026 by the GCB (German Convention Bureau), the DZT (German National Tourist Board) and the EVVC (European Association of Event Centres), Germany hosted 2.02 million in-person events in 2025, the same number as the year before. Attendance still rose to 395.1 million, so the growth came from larger events rather than more of them. Larger events need larger venues, and Germany has many, spread across many cities.
If you need the overall size of the market rather than a map of its cities, how big the MICE market is in 2026 sets out the global estimates and explains why they differ by so much.
The leading German cities by the numbers
So which cities sit behind the 565 congresses? ICCA’s European city ranking is the only public source that compares German destinations with one consistent method.
ICCA city ranking 2025
International association congresses in German cities
Only international association meetings are counted that take place regularly, rotate between at least three countries and attract at least 50 participants. Trade fairs and corporate events are excluded.
The ten cities in the chart account for 336 congresses. The remaining 229, about 40 per cent, are spread across a long tail, from Mainz with 11 and Bonn and Hanover with 10 each down to Bamberg, Bayreuth and Erfurt with three each. Behind the figures are four distinct profiles.
Berlin: Germany’s leading congress city
Berlin ranks eighth in Europe and twelfth worldwide, with twice as many congresses as Munich. ICCA singles the city out in its 2025 report as one of the strongest performers, “climbing significantly in the rankings”. That is notable because Berlin no longer runs a single flagship congress centre since the closure of the ICC Berlin. It relies instead on a decentralised mix of exhibition grounds, hotels and special venues.
Berlin wins on density, not on one building. Federal politics, association headquarters, research institutions and a start-up scene share one city, and ICCA ranks Berlin eighth worldwide for medical sciences meetings.
Munich, Hamburg, Frankfurt: congress and exhibition on one site
The next three cities combine both formats. Munich has the ICM (International Congress Center Munich) next to its exhibition grounds, Hamburg has the CCH (Congress Center Hamburg), which reopened in 2023 after modernisation, and Frankfurt has the congress centre of Messe Frankfurt. Together with Berlin, Cologne, Stuttgart and Nuremberg, the venues in these cities market themselves jointly as SevenCenters of Germany, a sign that the big locations see their competition in Europe rather than in each other.
With 56, 35 and 27 congresses, the three sit well behind Berlin. For a congress with a large industry exhibition, they are often the better choice anyway, because the plenary and the exhibition stay under one roof.
Cologne, Düsseldorf, Hanover, Stuttgart: trade fair heavyweights
Germany is the world’s leading trade fair country. According to AUMA (the Association of the German Trade Fair Industry), two thirds of the world’s leading trade fairs take place in Germany, at 70 venues with 3.25 million square metres of hall space, a fifth of Europe’s capacity (AUMA, March 2026).
The congress ranking shows little of this. Cologne hosted 22 congresses, Düsseldorf 18, Stuttgart 13 and Hanover 10, even though Hanover runs one of the largest exhibition grounds in the world. The reason is the counting rule: ICCA explicitly excludes trade shows and exhibitions. For a trade fair with a hosted buyer programme, these cities sit at the top of any list. For a rotating medical congress with 800 delegates, often not.
Dresden, Leipzig, Heidelberg, Bonn: science as a location factor
The fourth group punches above its venue size. Dresden (20), Leipzig (17), Heidelberg (16) and Bonn (10) have smaller congress centres than the trade fair cities, yet match or beat them in the congress ranking. Their argument is research: Dresden with its institutes and semiconductor industry, Heidelberg with its university, university hospital and research centres, Bonn as a UN city with more than 25 United Nations organisations on its campus, according to the City of Bonn.
International association congresses follow their discipline. For a cardiology congress, a cluster of specialist clinics nearby can matter more than the size of the plenary hall.
These are also the cities that industry analyses describe as the second-city trend: smaller destinations that compete on availability, lower costs and a clear profile. Our MICE tourism strategic guide for 2026 explains why planners are adding such cities to their shortlists.
For the congress director, this changes the list. Heidelberg or Dresden belongs next to Berlin. No ranking says so on its own.
Which ranking answers which question
That Hanover ranks low for congresses and high for trade fairs is not an anomaly. Several data sources describe the German market, and each answers a different question. Before you quote one to a council or a client, know which.
| Source | What it counts | What it leaves out | Good for the question |
|---|---|---|---|
| ICCA Country & City Rankings | International association meetings that take place regularly, rotate between at least three countries and have at least 50 participants | Trade fairs, corporate events, national congresses, one-off events | Where do international specialist congresses go? |
| UIA International Meetings Statistics | International meetings by a broader definition, including non-rotating ones | Corporate events, trade fairs | How international is a city overall? |
| Meeting- & EventBarometer (GCB, DZT, EVVC) | The whole German events market, including corporate events and national meetings | Any ranking by city | How big is the market, and where is it heading? |
| AUMA trade fair statistics | Trade fairs, exhibitors, visitors, hall space | Congresses and meetings without an exhibition | Where are the big exhibition cities? |
Vienna shows how far the counting methods can diverge. ICCA counted 159 congresses there in 2025, while the UIA (Union of International Associations) counted 345 international meetings for the same year, as Boardroom reported in July 2026. Both are correct. They measure different things.
For the congress director, this table answers the council’s first question. Berlin’s twelfth place describes one type of event. It says nothing about corporate meetings, national congresses or incentives.
Getting delegates to Germany: access and entry
A ranking tells you where congresses go. Your delegates care about how they get there, and this is where Germany’s network of cities has a hub. Frankfurt Airport handled about 63.2 million passengers in 2025, with 94 airlines serving 301 destinations in 96 countries (Fraport, January 2026). Munich is the country’s second long-haul hub.
For an international congress this matters twice. A direct flight lowers the barrier for delegates from distant member countries. A good rail connection from the hub opens up second cities that have no long-haul flights of their own. Ask every candidate city how delegates from your three largest member countries would actually travel, door to door.
Entry is the second check. Germany is part of the Schengen area, so delegates from many countries need a Schengen visa for a short business stay, and many will ask you for an invitation letter. How to issue those letters consistently and in good time is covered in our guide to visa invitation letters for event organisers. Since 10 April 2026, the EU Entry/Exit System (EES) has also been fully operational at Schengen external borders and registers non-EU short-stay travellers biometrically, which can lengthen arrival queues. Our EES guide for organisers shows how to build that into arrival day and what is still pending for ETIAS (the European Travel Information and Authorisation System).
None of this differs between Berlin and Bamberg. The visa and the border are the same for every German city, so the choice of city stays a question about your event.
How to shortlist a German city for your event
With access settled, start with the type of event, not with the ranking.
- Rotating international congress: The ICCA list is the right guide here. Then check whether the city has research strength in your field. Heidelberg or Dresden often beat bigger cities for a scientific congress.
- Trade fair or congress with a large exhibition: Look at exhibition cities such as Cologne, Düsseldorf, Hanover, Frankfurt or Munich, whose strength barely shows in the congress ranking.
- Corporate meeting or incentive: No ranking covers this market by city. Ask the convention bureau about capacity, side programme and access, and ask for references from your industry.
Then put the same questions to every bureau on your list. What support does it offer beyond the welcome reception? Which local experts could carry your bid, a role we describe in our article on congress ambassador programmes? And what will the bureau do after the award to help fill the hall, the work known as delegate boosting?
The congress director now has three candidates and a reason for each. That was the council’s brief.
What German convention bureaus can take from this
The same spread that gives planners choice gives destinations a problem: no German city wins on size alone. A clear, provable profile is what brings in the right events and partners.
That works best with numbers the ranking cannot supply. Which disciplines did your congresses come from over the past five years? Which of them came back? How many business contacts formed between visiting buyers and suppliers from the region? The last question is the one a city council understands most easily, because it shows the benefit to the local economy directly.
Many destinations answer it with their own formats: workshops, roadshows and hosted buyer programmes, in which invited buyers follow a fixed schedule of meetings with hotels, venues and agencies from the region. How such a programme is built, from invitation to meeting matrix, is explained in what a hosted buyer programme is.
Solution: Convention bureaus and tourism organisations use the Converve platform for tourism events to match buyers with regional suppliers before the event, schedule one-to-one meetings against a configurable meeting matrix and report afterwards on the meetings held per buyer and supplier. Those are results a general destination ranking cannot show.
Conclusion: choose the city by event type
Germany ranks third in the world for international congresses, but its strength is spread out. Berlin leads clearly, followed by congress and exhibition cities such as Munich, Hamburg and Frankfurt, trade fair heavyweights with modest congress counts, and science cities that win on their academic profile. Which German city is the best MICE destination depends on the event you plan and the ranking you read.
For planners, that means defining the event type first and choosing the matching ranking second. For convention bureaus, it means proving their profile with numbers no ranking provides: returning congresses, disciplines and the business contacts made on site.

Frequently Asked Questions
Which German city is the largest MICE destination?
For international association congresses, it is Berlin, with 112 congresses in 2025, eighth in Europe and twelfth worldwide (ICCA GlobeWatch 2025). Munich (56), Hamburg (35) and Frankfurt am Main (27) follow at a clear distance. For trade fairs the picture is different: Hanover, Frankfurt, Cologne, Düsseldorf and Munich are the leading exhibition cities.
Which cities in Germany are best for international congresses?
By the ICCA 2025 ranking, the leading cities are Berlin, Munich, Hamburg, Frankfurt am Main, Cologne, Dresden, Düsseldorf, Leipzig, Heidelberg and Stuttgart. Which is best for you depends on your discipline: science cities such as Heidelberg (16 congresses), Dresden (20) or Bonn (10) often suit specialist congresses better than larger cities.
Where does Germany rank internationally for congresses?
Germany ranked third worldwide in 2025 with 565 international association congresses, behind the United States (792) and Italy (616), according to ICCA. Unlike Portugal or Austria, Germany has no dominant congress capital: Berlin and Munich together account for just under 30 per cent.
Why do trade fair cities like Hanover rank low in congress rankings?
Because ICCA explicitly excludes trade shows. Its ranking counts only international association meetings that take place regularly, rotate between at least three countries and attract at least 50 participants. Hanover therefore shows 10 congresses (ICCA 2025), although it runs one of the largest exhibition grounds in the world. For trade fairs, AUMA statistics are the right source.
Do international delegates need a visa for a congress in Germany?
That depends on their nationality. Germany applies the Schengen rules, so citizens of many countries need a Schengen visa for a short business stay, and they often ask the organiser for an invitation letter. Since 10 April 2026, non-EU short-stay travellers are also registered in the EU Entry/Exit System at their first Schengen border crossing, so plan extra time on arrival day.
