Akrotiri and Dhekelia, officially the Sovereign Base Areas of Akrotiri and Dhekelia, is a British Overseas Territory on the island of Cyprus. The areas, which include British military bases and installations, as well as other land, were retained by the British under the 1960 treaty of independence, signed by the United Kingdom, Greece, Turkey and representatives from the Greek and Turkish Cypriot communities, which granted independence to the Crown colony of Cyprus. The territory serves an important role as a station for signals intelligence and provides a vital strategic part of the United Kingdom communications gathering and monitoring network in the Mediterranean and the Middle East.
The territory comprises two Base Areas. One is Akrotiri, or the Western Sovereign Base Area (WSBA), which includes two main bases at RAF Akrotiri and Episkopi Cantonment, plus all of Akrotiri Village's district (including Limassol Salt Lake) and parts of eleven other village districts. The other area is Dhekelia Cantonment, or the Eastern Sovereign Base Area (ESBA), which includes a base at Ayios Nikolaos plus parts of twelve village districts.
