In the west of Montenegro, at the field of Niksic, is the city of Niksic. Built in the 4th century, its original name was Onogost. Remains of this old city are today a cultural and historic monument. In the vicinity of Niksic, from the direction of Podgorica, high in the cliffs, is the greatest spiritual centre of Montenegro, the Monastery of Ostrog. Founded in the12th century by Metropolitan Vasilijethat, who was later proclaimed Saint and miracle worker. Today his relics are here and Ostrog is the most visited Orthodox shrine in the Balkans. In the city itself is the monumental Saborna Church, dedicated to Saint Vasilije and surrounded by a beautiful park. Niksic is flanked by three lakes: Krupac, Slano and Liverovici Lake. During the summer months these lakes are the main places for day trippers and holiday makers. Niksic is also well known for its production of the famous Niksicko beer.
