## Administrative divisions

The department of Plateau was created in 1999 when it was split off from Ouémé Department. It has an area of 2,835 square kilometres (1,095 sq mi). Plateau is subdivided into five communes, each centered at one of the principal towns: Adja-Ouèrè, Ifangni, Kétou, Pobè and Sakété.
Benin originally had six administrative regions (départements), which have now been bifurcated to make 12. Each of the deconcentrated administrative services (directions départementales) of the sectoral ministries takes care of two administrative regions. A law passed in 1999 transformed the sous-prefectures, the lowest level of territorial administration, into local governments. Municipalities and communal councils have elected representatives who manage the administration of the regions. The latest elections of the municipal and communal councils were held in June 2015.
