The Church of the Pantanassa (Greek: Εκκλησία της Παντανάσσης) or of the Dormition of the Theotokos (Ιερός Ναός Κοιμήσεως της Θεοτόκου) is the 10th-century katholikon of a now-vanished monastery in Monastiraki Square, between Athinas and Mitropoleos streets, facing the Monastiraki station, in central Athens, Greece. The church was known as the Great Monastery,^[1] and then later as monastiraki ("little monastery"), which eventually became the name of the whole area.^[2]
