The Luberon or Luberon Massif also called Lubéron, has a maximum altitude of 1,256 m and an area of about 600 km². It is composed of three mountain ranges: (from west to east) the Little Luberon, the Big Luberon and the Oriental Luberon, lying in the middle of Provence in the far south of France. The valleys north and south of them contain a number of towns and villages as well as agricultural land.
The total number of inhabitants varies greatly between winter and summer, due to a massive influx of tourists during the warm season.
It is a favourite destination for French high society and British and American visitors because of the pleasant and picturesque towns and villages, comfortable way of life, agricultural wealth, historical and cultural associations (e.g., Samuel Beckett lived in Cave Bonelly, a vineyard near to Roussillon during World War II), and hiking trails.
In the 1970s, people came from all over France to "Le Luberon" in search of a communitarian ideal.
The Force de frappe or French strategic nuclear arsenal used to be nearby, underground, on "Le Plateau d'Albion" before being dismantled in the late 1980s. Now, the underground site, where the control of the missiles was, is a public multidisciplinary laboratory of the University of Nice Sophia Antipolis, the Low Noise Underground Laboratory (LSBB) of Rustrel, Pays d'Apt.
In the last two decades the Luberon has become known in the English-speaking world especially through a series of books by British author Peter Mayle chronicling his life as an expatriate settled in the Luberon village of Ménerbes. These are titled A Year in Provence, Toujours Provence, and Encore Provence. Another of Mayle's books, a novel set in the Luberon, was made into a film called A Good Year (2006) directed by Ridley Scott, starring Russell Crowe and filmed in the region.
