Keila väikelinnuse, a small fortified site located in Keila, Harju County approximately 25 km southwest of Tallinn, represents an important archaeological site from medieval Estonia's early development. Archaeological excavations conducted in 1993 recovered artifacts now preserved in the Harjumaa Museum, with evidence suggesting fortification activity around 1301. The broader Keila area features significant ecclesiastical architecture, including a square chapel built around 1280 on Keila hill and the main body of Keila church, probably constructed at the beginning of the 14th century. These structures collectively demonstrate the gradual Christianization and fortification of northern Estonia during the medieval period, providing valuable archaeological evidence of settlement patterns during the transition from pagan to Christian rule.
