Koekelberg in the context of "Simonis and Elisabeth stations"

Line 5 is a rapid transit line on the Brussels Metro in Belgium operated by STIB/MIVB. It connects Herrmann-Debroux in the south-east of Brussels to Erasme/Erasmus in the south-west via the city centre. It has existed in its current form since 4 April 2009, when the section of former line 1A between Beekkant and Roi Baudouin/Koning Boudewijn was replaced by the section of former line 1B between Beekkant and Erasme. Starting from Herrmann-Debroux, the line crosses the municipalities of Auderghem, Etterbeek, City of Brussels, Molenbeek-Saint-Jean, Koekelberg and Anderlecht. It serves 28 metro stations and has a common section with line 1 between Gare de l'Ouest/Weststation and Merode, and with lines 2 and 6 between Gare de l'Ouest and Beekkant. At Arts-Loi/Kunst-Wet, the line also connects with lines 2 and 6. Railway connections are possible at Brussels-Central, Brussels-Schuman, Merode and Brussels-West.

The first section of this line was built in the late 1960s between Schuman and De Brouckère, but was served by trams. The first metro was brought into service on 20 September 1976, and the existing underground section was extended up to Tomberg on former line 1B, and up to Beaulieu on former line 1A. Line 1A was further expanded eastwards, to Demey in 1977 and to Herrmann-Debroux in 1985. The line was also expanded westwards, to Sainte-Catherine/Sint-Katelijne in 1977, to Beekkant in 1981, to Bockstael in 1982, to Heysel/Heizel in 1985 and to Roi Baudouin in 1998.

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.

Line 1 is a rapid transit line on the Brussels Metro in Belgium operated by STIB/MIVB. It has existed in its current form since 4 April 2009, when former line 1B, which ran between Stockel/Stokkel and Erasme/Erasmus, was shortened to Gare de l'Ouest/Weststation. The section between Gare de l'Ouest and Erasme is now served by line 5. The line serves 21 metro stations, and has a common section with line 5 between Gare de l'Ouest and Merode, and with lines 2 and 6 between Gare de l'Ouest and Beekkant. At Arts-Loi/Kunst-Wet, the line also connects with lines 2 and 6. Railway connections are possible at Brussels-Central, Brussels-Schuman, Merode and Brussels-West. The line crosses the municipalities of Molenbeek-Saint-Jean, Koekelberg, City of Brussels, Etterbeek, Woluwe-Saint-Pierre and Woluwe-Saint-Lambert.

The first section of this line was built in the late 1960s between Schuman and De Brouckère, but was served by trams. The first metro was brought into service on 20 September 1976, and the existing underground section was extended up to Tomberg on former line 1B, and up to Beaulieu on former line 1A. Line 1B was later expanded westwards, to Sainte-Catherine/Sint-Katelijne in 1977, to Beekkant in 1981, to Saint-Guidon/Sint-Guido in 1982, to Veeweyde/Veeweide in 1985, to Bizet in 1992 and finally to Erasme in 2003. The line was also expanded eastwards, to Alma in 1982 and to Stockel in 1988.

Line 2 is a rapid transit line on the Brussels Metro in Belgium operated by STIB/MIVB. It has existed in its current form since 4 April 2009, when the section between Delacroix and Gare de l'Ouest/Weststation was opened, which allowed to close the "loop" from and to Simonis/Elisabeth. The configuration of Simonis/Elisabeth though does not allow trains on line 2 to perform the loop several consecutive times in the same direction, i.e. a train running clockwise from Elisabeth will have to run counterclockwise from Simonis. The two termini of line 2 have thus received different names: originally Simonis (Elisabeth) and Simonis (Leopold II), changed in November 2013 to Elisabeth and Simonis. Between Yser/IJzer and the Porte de Hal/Hallepoort, the line runs under the Small Ring (Brussels' inner ring road), which was itself built on the site of the former second walls of Brussels. The line crosses the municipalities of Koekelberg, Molenbeek-Saint-Jean, City of Brussels, Saint-Gilles and Anderlecht.

The first stations on the Small Ring were opened in 1970 with tramways connecting Rogier to Porte de Namur/Naamsepoort. Louise/Louiza was opened in 1985 and Simonis in 1986, but it was only in 1988 that the actual metro line 2 was first serviced with metros. The following stations also opened that year: Ribaucourt, Yser, Hôtel des Monnaies/Munthof, Porte de Hal and Gare du Midi/Zuidstation. The existing stations were converted in order to be serviced by metros. In 1993, the line was expanded to Clemenceau, and then to Delacroix in 2006. The route of line 2 is also currently served by line 6, which then continues from Simonis to Roi Baudouin/Koning Boudewijn.

Line 6 is a rapid transit line on the Brussels Metro in Belgium operated by STIB/MIVB. It connects Roi Baudouin/Koning Boudewijn in the north-west of Brussels to Simonis/Elisabeth to the north-west of the city centre, then performing a counterclockwise "loop" around the centre up to Simonis again. During this loop, the line runs under the Small Ring (Brussels' inner ring road), from Porte de Hal/Hallepoort to Yser/IJzer. It has existed in its current form since 4 April 2009, when it replaced former line 1A between Roi Baudouin and Beekkant. It serves 25 metro stations and has 26 stops, metros on that line stopping twice at Simonis. The Simonis-Elisabeth loop is also served by line 2. The line has also a common section with lines 1 and 5 between Gare de l'Ouest/Weststation and Beekkant. A connection with those lines is also possible at Arts-Loi/Kunst-Wet. Starting from Roi Baudouin, the line crosses the municipalities of the City of Brussels, Jette, Koekelberg, Molenbeek-Saint-Jean, Anderlecht and Saint-Gilles.

Molenbeek-Saint-Jean (French, pronounced [molœnbek sɛ̃ ʒɑ̃] ) or Sint-Jans-Molenbeek (Dutch, pronounced [sɪɲˈtɕɑns ˈmoːlə(m)ˌbeːk] ), often simply called Molenbeek, is one of the 19 municipalities of the Brussels-Capital Region, Belgium. Located in the western part of the region, it is bordered by the City of Brussels, from which it is separated by the Brussels–Charleroi Canal, as well as by the municipalities of Anderlecht, Berchem-Sainte-Agathe, Dilbeek, Jette, and Koekelberg. The Molenbeek brook, from which it takes its name, flows through the municipality. In common with all of Brussels' municipalities, it is legally bilingual (French–Dutch).

From its origins in the Middle Ages until the 18th century, Molenbeek was a rural village on the edge of Brussels, but around the turn of the 19th century, it experienced major growth brought on by a boom in commerce and manufacturing during the Industrial Revolution. Its prosperity declined after the Second World War, owing to deindustrialisation, leading to extensive investment and regeneration. Experiencing a strong movement of immigration, mainly Moroccan, from the 1950s and 1960s, Molenbeek became increasingly multicultural with a minority Muslim population. In the 2010s, it gained international attention as the base for Islamist terrorists who carried out attacks in both Paris and Brussels.

Berchem-Sainte-Agathe (French, pronounced [bɛʁkɛm sɛ̃t aɡat] ) or Sint-Agatha-Berchem (Dutch, pronounced [sɪnt aːˈɣaːtaː ˈbɛrxɛm] ), often simply called Berchem, is one of the 19 municipalities of the Brussels-Capital Region, Belgium. Located in the north-western part of the region, it is bordered by Ganshoren, Koekelberg, and Molenbeek-Saint-Jean, as well as the Flemish municipalities of Asse and Dilbeek. In common with all of Brussels' municipalities, it is legally bilingual (French–Dutch).

As of 1 January 2024, the municipality had a population of 25,787 inhabitants. The total area is 2.95 km (1.14 sq mi), which gives a population density of 8,741/km (22,640/sq mi). The municipality is known for its calm and peaceful character. It is said that Berchem is a "village in the city".

In common with all of Brussels' municipalities, it is legally bilingual (French–Dutch).

As of 1 January 2024, the municipality had a population of 54,107 inhabitants. The total area is 5.19 km (2.00 sq mi), which gives a population density of 10,427/km (27,010/sq mi).
