The Dead Cities or Forgotten Cities are a group of 700 abandoned settlements in northwest Syria between Aleppo and Idlib. Around 40 villages grouped in eight archaeological parks situated in north-western Syria provide an insight into rural life in Late Antiquity and during the Byzantine period. Most of the villages, which date from the 1st to 7th centuries, were abandoned between the 8th and 10th centuries. The settlements feature the well-preserved architectural remains of dwellings, pagan temples, churches, cisterns, bathhouses etc. Important dead cities include the Church of Saint Simeon Stylites, Serjilla and al Bara.
The Dead Cities are situated in an elevated area of limestone known as Limestone Massif. These ancient settlements cover an area 20–40 km wide and some 140 km long.
