The town of Ston on the Peljesac Peninsula sits at the base of the peninsula and is the closest town to the mainland. It was originally settled by the Romans and was called Stagnum. Ston's most impressive feature is the defensive wall from the 14th and 15th Centuries. More than 5km / 3mi of the wall still remains and is relatively intact for
having been bombed in the 1991 war and struck by an earthquake in 1996.
Ston is divided into sections. Veliki Ston is the main area of town near the waterfront and further back is Mali Ston. The two areas, each on opposite sides of the peninsula, are connected by the defensive wall. Velike Ston is where visitors will find most of the major attractions including the large fort of Velike Kastio, the neo-Gothic St Blaise Church (Sv Vlaho), the Governor's Palace (Knezev Dvor), the Bishop's Palace, and the Franciscan Church and Monastery of St Nicholas (Franjevacki Samostan), built between the 14th and 16th Centuries. The main attraction in Mali Ston is the 15th Century, Fort Koruna.
