The ancient gate of Zagreb, also known as the Stone Gate, is located near St. Mark's Church. Stone Gate was built in Roman times and is the only well-preserved city gate in the old city. There is an iron gate in the passage of the stone gate, in which the statue of the Virgin Mother and the Son is worshipped. Old people passing by stop here to pray. There is a statue of a knight riding outside the stone gate. Don't miss it.
