Aix-en-Diois (French pronunciation: [ɛks ɑ̃ diwa]; Vivaro-Alpine: Ais de Diés) is a former commune in the Drôme department in southeastern France. On 1 January 2016, it was merged into the new commune Solaure-en-Diois.^[2]

History

Aix-en-Diois belonged to the counts and later to the bishops of Die (twelfth century). Later, it belonged to the Princes of Orange, and finally to the La Tour du Pin family (seventeenth century). The commune contains the remains of Roman baths and the ruins of a 13th-century medieval castle with a polygonal enclosure and corner towers, rebuilt in the 16th century.^[3] The castle hall dates from the 17th century and is the former summer residence of the Bishop of Die. The main church is the Church of the Immaculate Conception.
