Neder-Over-Heembeek in the context of Vilvoorde

The City of Brussels is the largest municipality and historical centre of the Brussels-Capital Region, as well as the capital of the French Community of Belgium, the Flemish Region (from which it is separate) and Belgium. The City of Brussels is also the administrative centre of the European Union, as it hosts a number of principal EU institutions in its European Quarter.

Besides the central historic town located within the Pentagon, the City of Brussels covers some of the city's immediate outskirts within the greater Brussels-Capital Region, namely the former municipalities of Haren, Laeken, and Neder-Over-Heembeek to the north, as well as the Avenue Louise/Louizalaan and the Bois de la Cambre/Ter Kamerenbos park to the south-east, where it borders municipalities in Flanders.

The 19 municipalities of the Brussels-Capital Region are the political subdivisions of Belgium's central region. The government of each municipality is responsible for the handling of local level duties, such as law enforcement and the upkeep of schools and roads within its borders. Municipal administration is also conducted by a mayor, a council, and an executive.

In 1831, Belgium was divided into 2,739 municipalities, including 20 within the current Brussels-Capital Region (which at that time did not exist). In 1841, a 21st and 22nd municipality were created when Berchem-Sainte-Agathe formally separated from neighbouring Koekelberg and Jette-Ganshoren split into Jette and Ganshoren. Since then, three municipalities have been merged with the City of Brussels: Laeken, Haren, and Neder-Over-Heembeek, in 1921. Unlike most of the municipalities in Belgium, the ones located in the Brussels-Capital Region were not merged with others during mergers occurring in 1964, 1970, and 1975. However, many territorial changes have occurred, predominantly between the City of Brussels and its neighbouring municipalities.

The premetro and tram route 10 in Brussels, Belgium, is operated by STIB/MIVB, and connects the Hôpital Militaire/Militair Hospitaal stop in Neder-Over-Heembeek in the City of Brussels to the Churchill stop in the southern municipality of Uccle. It began service on 23 September 2024, taking over most of the route of line 3, which was disbanded that day.

The premetro and tram route 3 in Brussels, Belgium, was operated by STIB/MIVB, and connected the Esplanade stop (on the borders of Neder-Over-Heembeek in Laeken in the City of Brussels and Strombeek-Bever) with the Churchill stop in the southern municipality of Uccle. The line was named after the planned Metro line 3, which is set to service most of the former route of tram line 3. The colour of the signage for this line was lime-green.

On 23 September 2024, the line was permanently disbanded, with most of its route being taken over by the new line 10. A further tram line 35 was established, taking over the Esplanade–Van Praet portion of line 3 and continuing on to a new terminus at Bienfaiteurs/Weldoeners.
