Central St. Stephen's square in the city of Hvar or Piazza is the largest square in Dalmatia. Originally it was a deep bay which was filled with rocks for centuries until it got its present dimensions. Subsequently, it was a space between two fortified cities: Groda on the north and Burg in the south. By the 15th century Piazza was formed with the cathedral in the east and sea in the west. It used to be wider than it is presently but due to shortage of space in the fortified city, houses were built on the northern part of Piazza in front of the city walls. Communal well in the center of Piazza dates from 1520. Piazza was fully paved in 1780.
