Belgian Parliament Opens Doors for National Day

On Tuesday, July 21, 2026, the Belgian Federal Parliament — comprising the Chamber of Representatives and the Senate — will open its doors to the general public for a free behind-the-scenes visit in celebration of Belgium’s National Day. Visitors will have the rare opportunity to explore the historic Palace of the Nation (Palais de la Nation) in Brussels, including its monumental staircase, historical rooms, and the hemicycles of both chambers, from 11:00 AM to 7:00 PM with free entry.

A Rare Glimpse into Belgian Democracy

The annual open house, announced jointly by the Chamber and the Senate on Friday, July 17, offers citizens a unique chance to discover the inner workings of one of the country’s most important institutions. According to La Libre Belgique, the event allows visitors to explore the monumental staircase, walk through historical rooms, and visit the hemicycle of both assemblies.

This year’s edition features a special exhibition dedicated to the Belgian flag — black, yellow, and red — with artworks draped in the national colors winding through the Palace of the Nation. As 7sur7 reports, the Belgian flag will be honored during the national day at the Palace of the Nation through its representation in works of art.

Activities for All Ages

Visitors of all ages can explore the parliamentary buildings at their own pace, guided by brochures and quizzes. The self-guided tour route will be enhanced with musical interludes, an expression wall where visitors can leave their thoughts, and a photobooth to capture the experience. Entry is via Place de la Nation, near the rainbow crosswalk on Rue de la Loi, opposite Brussels Park.

The Palace of the Nation: A Historic Venue

The Palace of the Nation, built between 1778 and 1783 in neoclassical style by French architect Gilles-Barnabé Guimard, has been the home of the Belgian Parliament since the country’s independence. According to Wikipedia, the building originally served as the seat of the Sovereign Council of Brabant under Austrian rule before housing the Provisional Government and National Congress after the Belgian Revolution of 1830. The first session of the Chamber of Representatives and Senate was held there in 1831, the same year King Leopold I took the constitutional oath on July 21 — the date now celebrated as Belgium’s National Day.

Broader National Day Celebrations

The Parliament’s open house is just one part of a full day of National Day festivities across Brussels. According to the Belgian Federal Public Service for Interior Affairs, the celebrations include a security services village at Place Poelaert, Place Royale, and Sablon (10 AM – 8 PM), the traditional military and civil parade at Place des Palais in the afternoon, and an evening concert and drone show at Cinquantenaire Park. The day concludes with a traditional fireworks display attended by the royal family. The European Commission Representation in Belgium is also hosting a “European Village” at the Sablon with activities focused on democracy and European defense.

Why It Matters

Belgian National Day commemorates the oath of office taken by King Leopold I on July 21, 1831, marking the consolidation of Belgian independence following the revolution of 1830. The Parliament’s open house serves multiple purposes: promoting democratic transparency by allowing citizens to see the inner workings of their legislative institutions, providing civic education through guided tours and quizzes, and celebrating national identity as part of the broader festivities. The current King Philippe took his own constitutional oath before the United Chambers on July 21, 2013, continuing a tradition that links the monarchy, parliament, and the people.

What to Know Before You Go

The open house runs from 11:00 AM to 7:00 PM on Tuesday, July 21, 2026, with free admission. Entry is through Place de la Nation, easily accessible from Brussels Park. No reservation is required, and the self-guided format allows visitors to explore at their own pace with the help of informational brochures and quizzes. The flag-themed exhibition, musical performances, and interactive installations make this year’s edition particularly family-friendly.

For those unable to attend, the National Day parade and evening festivities will be broadcast live on national television channels.
