Toompea (from German: Domberg, "Cathedral Hill") is a hill in the central part of Tallinn, the capital city of Estonia. The hill has an area of 7 hectares (17 acres) and is about 20–30 metres higher than the surrounding areas. Toompea is part of the medieval Tallinn Old Town, a UNESCO World Heritage Site.
Toompea is the site of the Government of Estonia and the Riigikogu (parliament), both of which are often simply referred to as Toompea. The parliament meets in the Toompea Castle which is situated in the southwestern corner of the hill and topped by the Pikk Hermann ("Tall Hermann") tower. The flag on the top of the tower is one of the best-known symbols in Estonia of the government in force.
