St. Mark's Square is located in the old part of Zagreb, called Gradec or Gornji Grad. In the center of the square stands St. Mark's Church. Located nearby are several government buildings: Banski Dvori (the seat of Croatian Government), The Croatian Parliament and The Constitutional Court of Croatia.
