This museum shows how wealthy bourgeois families lived in Aachen in the 18th and 19th centuries. It is named after Johann Joseph Couven (1701–1763) and his son Jakob Couven (1735-1812), both of whom were prominent architects in Aachen.
Those who have read my post On the Wings of Song might recall that Jakob Couven was the architect who built the Old Kurhaus (as it is now called) in 1782.
