Arts-Loi/Kunst-Wet is a Brussels metro station in the City of Brussels, Brussels. It is the only station in the metro network where all four lines (1,2,5,6) meet. 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 December 17, 1969, but at that time the station served tram rather than railway lines. The first metro train stopped here on September 20, 1976. There was then only one metro line (line 1) split into two branches at Mérode.
