Based on the number and quality of buildings and artistic works, it appears that the small area of Ston was more expressive then other areas of Peljesac. Near Broce and Kobaš to the southeast, is the most potruding promontory on Pelješac, enclosing the long, narrow Ston Bay.Here Illyrian established their reconnaissance and guard stations facing the open sea, and central Gradina facing the fertile Vinopolje.The Romans then erected guard stations here, next to the saltpans, where stone and earth bulwarks with pole fences extended as part of their defence system.The original stone wall project was not completed, according to 1478 plans - so this lake-like ambience naw includes low one-storey stone houses, along with the small churches of St Felician and All Saints located near the cemetery.Of greater value is the complex of the Dominican monastery with the Church of Annunciation built in 1629 and long since deserted.Worth mentioning are the summerhouses of writer Betondić and gunsmith Ivan Rabljanin located at Jelinjak near Kobaš. Both are examples of late Renaissance Dubrovnik architecture.
