The station is located in the municipality of Saint-Gilles, south of the City of Brussels, under the Small Ring (Brussels' inner ring road) and next to the 14th-century Halle Gate, after which it is named.

It is one metro stop away or about ten minutes' walk from Brussels-South railway station.

The metro station opened on 2 October 1988 as part of the Louise/Louiza–Gare du Midi/Zuidstation extension of line 2 from Simonis.

Then, following the reorganisation of the Brussels Metro on 4 April 2009, it is served by lines 2, 3, 4 and 6.
