Immediately after the War The Saint-Germain-des-Pres quarter and the nearby Saint-Michel quarter became home to many small jazz clubs, mostly found in cellars because of a lack of space; these included the Caveau des Lorientais, the Club Saint-Germain, the Rose Rouge, the Vieux-Colombier, and the most famous, Le Tabou.

Most of the clubs closed by the early 1960s, as musical tastes shifted toward rock and roll.
