Warsaw's Old Town (Polish: Stare Miasto, colloquially: Starówka) is the oldest historic district of the city. It is bounded by Wybrzeże Gdańskie, along the bank of the Vistula, and by Grodzka, Mostowa and Podwale Streets. It is one of Warsaw's most prominent tourist attractions. The heart of the area is the Old Town Market Place, with its restaurants, cafés and shops. Surrounding streets feature medieval architecture such as the city walls, the Barbican and St. John's Cathedral.
