Since
the 17th century, the charm of this village, named after a Muslim saint who
died in 1231 and whose tomb is still honored today, has seduced the Tunisian
bourgeoisie and the Husseinite Bey family. It became the seat of a municipality
in 1835. In 1915, a decree was issued to protect the village, imposing the blue
and white so dear to Baron d'Erlanger, a French-British painter, musicologist,
and great orientalist who built a 2,000m2 palace in a five-hectare garden, now
the "Center and Museum of Arab and Mediterranean Music." This decree
prohibits any anarchic construction on the promontory, making Sidi Bou Said the
world's first listed site.
