The EU Open Door Day Brussels event drew large crowds as citizens gathered to visit key European Union institutions in the Belgian capital. The event was held on May 9, 2026, to mark the 76th anniversary of the foundation of the European Union. It is part of the annual Europe Day celebrations, which promote unity and public awareness of the EU’s role.
Visitors formed long queues outside major buildings, including the European Commission headquarters. Many people waited for hours to enter and explore the institution. The event allowed the public to see how EU offices operate from the inside. It also gave citizens a chance to learn more about decision-making processes within the Union.
The Open Door Day included several major EU institutions. These included the European Parliament, the Council of the European Union, and the European Commission. All three organizations opened their headquarters to the public for guided visits, exhibitions, and interactive sessions. The aim was to make EU institutions more accessible and transparent to citizens.
The event took place in Brussels, which serves as the administrative heart of the European Union. Brussels hosts most of the EU’s main institutions, making it a central location for political and diplomatic activity in Europe. During Europe Day, the city becomes a focal point for celebrations and public engagement.
Many visitors said the experience helped them better understand how the European Union works. Exhibitions inside the buildings explained policies, legislation, and cooperation between member states. Staff members were present to answer questions and guide visitors through different sections of the institutions.
Families, students, and tourists were among those attending the event. Some visitors said they wanted to see where important European decisions are made. Others were interested in learning about EU history and its development over the past decades. The event is designed to make politics more open and easier to understand for the general public.
Security checks were in place at all entry points, but the atmosphere remained festive. Music, cultural displays, and educational activities were organized across different venues. Visitors were encouraged to interact with displays and participate in learning activities. The open format allowed people to explore at their own pace.
The EU Open Door Day is held every year as part of Europe Day celebrations. Europe Day marks the historic beginnings of European cooperation and unity after World War II. It is meant to highlight peace, integration, and shared values among European countries. The 2026 edition marked 76 years since the foundation of the European project.
Officials said the high turnout shows continued public interest in EU institutions. Many people see the event as a rare opportunity to enter buildings that are normally closed to the public. It also helps strengthen the connection between citizens and European governance structures.
The European Parliament and other institutions use the event to promote transparency. By opening their doors, they aim to show how policies are created and implemented. This helps build trust and understanding between EU bodies and the public they serve.
The event also included educational exhibitions about European history and cooperation. These displays highlighted key milestones in the EU’s development. They also focused on current challenges and future goals for the union. Visitors were able to explore how different countries work together on shared issues.
Despite long queues, many attendees described the experience as rewarding. The opportunity to see inside major EU institutions is rare, making the event popular each year. Organizers said they were pleased with the strong public participation.
The EU Open Door Day Brussels continues to be an important part of Europe Day celebrations. It reflects the European Union’s effort to remain open, transparent, and connected to its citizens while celebrating its long history of cooperation and unity.
