Toompea Castle (also Latin: Castrum Danorum, Estonian: Toompea loss; (previously probably) Taani loss, literally "The Danish castle") is a castle on the limestone hill of Toompea in the central part of Tallinn, the capital of Estonia, which for a time was also one of the names for the whole settlement of Tallinn during the times of Danish Estonia in the 13th and 14th centuries.
