The commune is situated at the exit of the water gap opened by the Durance in the limestone plateau that since the Middle Ages has been called the plateau of Saint-Sépulcre. The water gap of Mirabeau is used as a crossing the Durance, which for most of its length is wide and rapid. The village is situated between the communes of Pertuis and Manosque at a place where four departments meet:Vaucluse, Bouches-du-Rhône, Alpes-de-Haute-Provence and Var. It is on Route Départementale 973. Mirabeau village is in the Luberon Massif and is one of the 77 members of the parc naturel régional du Luberon.
The cantons of Bonnieux, Apt, Vaucluse, Cadenet, Cavaillon, and Pertuis are classified as Zone Ib. All the other cantons in the department of Vaucluse are classified as Zone Ia. Seismicity in these zones only exceptionally causes the destruction of buildings. Since April 2018 the castle is closed for public visitors, due to the risk.

History
Prehistory and antiquity
On the Saint-Sépulcre plateau the first traces of human occupation date from the La Tène culture in about 500 BCE. According to specialists, this defensive site, which has not been fully investigated, may hide other archaeological remains. The Gallo-Roman period is represented by a pottery kiln found at a place called Le Moulin. It would have provided Gallic amphoras and dolia to the villa near the Ferme de l’Étang where mosaics have been found.
Middle Ages
The first castrum was built at the beginning of the 12th century. It was in existence when a papal bull of Pope Gelasius II in 1199 confirmed Mirabel as a possession of the abbey Saint-André de Villeneuve-lès-Avignon. Fifty years later, a bull of Pope Alexander III renewed the rights of the Benedictines of Mont Andaon over Mirabello, with obligation to serve the priory consecrated to the Beate Mariae Magdalena de Ponte Cantus Pernicis. In 1189, the Hospitaliers du Pont de Bonpas, in order to control the passage by ferry over the Durance river in the gorge of Mirabeau built a house near the chapel dedicated to La Magdaleine. This chapel of Cante Perdrix, one of the oldest priories in Provence dedicated to La Magdaleine, became the place of worship of a guild of ferrymen on the Durance. Its façade still bears an inscription on the subject of a solar eclipse in the 13th century.
