Kunst-Wet (Dutch) or Arts-Loi (French) is a Brussels metro station in the City of Brussels. It is located under the intersection of "Rue de la Loi/Wetstraat" and "Avenue des Arts/Kunstlaan", the latter street being part of the "inner ring". The station's lower level was opened on 17 December 1969, although at that time the station served tram rather than railway lines. The first metro train stopped here on 20 September 1976. There was then only one metro line (line 1) split into two branches at Merode.
The station was extended in 1988 with the opening of the old line 2 station, located on the upper level. The station is mainly used by commuters as there are few tourist sites nearby, although as an important junction between lines, many users of the metro network change trains here.
