Long Tieng
Long Tieng (also spelled
Long Chieng,
Long Cheng, or
Long Chen) is a Laotian military base in
Xaisomboun Province. During the
Laotian Civil War, it served as a town and airbase operated by the
Central Intelligence Agency of the
United States. During this time, it was also referred to as ''Lima Site 98'' (LS 98) or ''Lima Site 20A'' (LS 20A).
At the height of its significance in the late 1960s, the "secret city" of Long Tieng maintained a population of 40,000 inhabitants, making it the second largest city in Laos at the time, although it never appeared on maps throughout this period.
