Square Prince Léopold - Prins Leopoldsquare

Square Prince Léopold – Prins Leopoldsquare is a compact but carefully designed public park in the Laeken district of Brussels, north of the Belgian capital's city centre. Covering roughly two hectares, it forms the green heart of a distinctive star-shaped neighbourhood laid out at the turn of the 20th century.

Where does the name come from and how is the district laid out?

The park sits at the centre of a district created by royal decree on 18 February 1899. Streets radiate outward from it toward Boulevard de Smet de Naeyer and Boulevard Émile Bockstael, as well as toward the western ring railway line, giving the neighbourhood its characteristic star pattern that is still clearly visible on a map of Laeken today. The square itself is bordered by eight streets, making it a natural reference point in this part of the district.

The park's name honours the future King of the Belgians, Leopold III, the first child of King Albert I and Queen Elisabeth, born in 1901. Naming the new public space after the newborn heir followed the common practice of the time of commemorating royal family events through freshly laid-out streets and squares.

What role did it play in Brussels' water management system?

Like Square Prince Charles to its southeast, Square Prince Léopold was built along the former course of the Molenbeek stream, which was covered over and channelled underground between 1904 and 1907. Beneath the park lies a large retention basin for the stream's water, designed in 1902 by engineer Jules Zone. The basin was intended to protect the surrounding streets, which were being densely built up at the time, from flooding caused by the stream, and it formed part of a broader plan to manage surface water in this part of the city.

Because of its historical and engineering significance, the site has been listed on the Brussels-Capital Region's heritage protection register since 2 April 1998.

What can visitors see there today?

The park is surrounded by Art Deco buildings, most of them erected during the 1930s, whose façades give the whole neighbourhood a coherent, period appearance. At the centre of the square stands a circular fountain, which serves as the park's visual focal point and a natural gathering spot for local residents.

The layout of lawns, paths and small play areas means the park today functions mainly as a recreational space for people living nearby — a place for a walk, a rest on a bench, or a short break while exploring this quieter, architecturally interesting corner of Laeken away from the busier tourist routes.

Frequently asked questions

Is Square Prince Léopold the same place as Leopold Park in the European Quarter? No. They are two different parks in Brussels — Square Prince Léopold is located in Laeken, in the north of the city, while the better-known Leopold Park (Parc Léopold) lies in the European Quarter, near the EU institutions.

Why does the park have a shape tied to a star-shaped street layout? This comes from the urban plan approved by royal decree in 1899, in which the park was designed as the central point from which the streets of the new neighbourhood radiate outward.

What lies beneath the park? Beneath the park is a retention basin for the former Molenbeek stream, designed in 1902 as part of the works to cover the stream between 1904 and 1907.

How do you get to Square Prince Léopold? The park is located in the Laeken district, bordered by eight streets near Boulevard de Smet de Naeyer and Boulevard Émile Bockstael — a quiet, residential part of the city, away from central Brussels' main tourist routes.
