Forcalquier is built around the slopes of a steep conical hill, crowned by an octagonal chapel, Notre Dame de Provence, where the medieval citadel once stood. The citadel was destroyed in 1601; the chapel was built in 1875 and offers a panoramic view of the landscape.

The oldest part of the medieval town is the area around the Place Saint-Michel with its Renaissance fountain (1511) and its narrow side-streets. There are many 12th to 16th century doorways to be found.

Noteworthy is the Musée Municipal with its prehistoric and Gallo-Roman artifacts, glass works, and faïence pottery from Mane, Apt and Moustiers-Sainte-Marie.

Monday morning is market day in Forcalquier. The market fills the Place du Bourguet and the adjoining streets.
