Things to do

Brussels splits in two: the old centre around the Grand-Place with its tight streets, and the upper town with the park and the royal museums. Distances are short, trams and metro link the districts, and walking carries you from the centre into Ixelles.

The Grand-Place and the galleries

On the Grand-Place see the town hall and the King's House, then walk through the Royal Galleries of Saint-Hubert. Look into the chocolate shop windows on the way and come out by the Cathedral of Saints Michael and Gudula.

Sablon and the Marolles

The Sablon quarter is known for its antique dealers and the Church of Our Lady of the Sablon. Walk down to the Palace of Justice and on into the Marolles, where the flea market fills the Place du Jeu de Balle.

The Atomium and Laeken

The Atomium in Laeken is worth seeing from inside, climbing through the tubes to the exhibition halls. Mini Europe and the royal greenhouses are nearby, so give the trip half a day.

Where to stay

Centre

The centre suits a short stay: the Grand-Place, the galleries and the cathedral are steps apart. Bars keep the streets busy at night, but Central station is close and every district is within walking distance.

Ixelles

Ixelles draws people for its cafés, bookshops and the Flagey market, where antiques are sold at weekends. The centre is twenty minutes on foot or a few tram stops away, and the district feels both livelier and calmer.

The European quarter

The European quarter around Schuman is built of institutional offices and glass towers. It is quiet in the evenings and practical for work, and the historic centre and Leopold Park are an easy walk away.

Getting to and around Brussels

Trains from Brussels Airport reach the Central station in about twenty minutes, while buses and taxis use the ring road. In the city the metro, trams and buses work well, with tickets from machines or a contactless card. The centre is compact enough that half of any route is better walked.

Three days in Brussels

Grand-Place and the lower town

Start on the Grand-Place with the town hall and the King's House, then walk through the Saint-Hubert galleries. See the cathedral and the Sainte-Catherine area in the afternoon and have dinner there in the evening.

Sablon and the Marolles

Walk through the Sablon past the antique dealers to the Church of Our Lady. After lunch go down to the Palace of Justice and into the Marolles for the flea market and its cafés.

Laeken and the park

Ride out to Laeken for the Atomium and walk through the park with its greenhouses. Return past the Royal Palace and cross Brussels Park down to the Grand-Place.
