Ston is 53 kilometres far away from Dubrovnik towards north-west and it has about 580 inhabitants. Ston consists of two fortified settlements of Veliki and Mali Ston. They are joint by the great wall that connects the peninsula with the continent. This wall is pentagonal shaped. The fortification called Veliki kastilo served as a wheat and ammunition repository. In the shallow bay at the back of the Ston canal there are salt pans. They brought a great profit to Dubrovnik Republic. In Veliki Ston the offices of Dubrovnik Republic were built, and also the renaissance court, the count court, the town faucet and the gothic cathedral that was knocked down by earthquake and on the place of which  there is a parochial church of St.Blaise. The Franciscan monastery is on the west side, and it was built in the middle of the fourteenth century. Mali Ston is famous by its breeding sites of bivalves, especially oysters. The St.Michael church is placed on the hill on the west side from Veliki Ston. It is famous by the preserved frescoes. The St.Nicholas church keeps numerous artistic objects.
