Montenegro has a tradition of art going back to prehistory, as testified to by the archaeological finds of paintings by prehistoric man in Lipci near Risan dating to the 8th century BC. The drawing represents a deer hunt, and also features a symbol of the rising sun and others. Another drawing has been discovered on a stone tablet in the Prokletije mountains in the north of Montenegro, depicting a prehistoric man and a wolf. The Crvena Stijena (Red Rock) site in Petrovići is around 30km from Nikšić and is considered one of the most important archaeological sites in Europe. Remains from the Middle Paleolithic, Mesolithic, Neolithic and Bronze ages have been found here, and are highly significant, testifying to the beginnings of life not just in this part of Montenegro but on the planet as a whole. For many years, local and foreign expeditions have been coming to this unique and internationally significant site. More than 26,000 items from the time of prehistoric man have been excavated here. A great many items used in everyday life have been discovered, such as for the procurement and preparation of food, but also non-utilitarian items. These include handmade stone items, snails and shells, as well as ceramic vessels. The numerous medieval fortresses in Montenegro are an art-form in their own right. They feature Byzantine, Romanic, Gothic and Baroque construction styles, as well as stone forms and paintings. Through the ages these fortresses have played a military and feudal role, or were built as town fortifications. They are built of stone and feature surrounding walls and towers. These fascinating structures were raised in numerous coastal towns, where Illyrian, Austro-Hungarian, Turkish and Spanish influences predominate, such as in Bar, Ulcinj, Herceg Novi, Budva, Kotor, Risan, Perast, as well as in the north of Montenegro: Rijeka Crnojevića, Podgorica and the Lake Skadar area. The National Museum at Cetinje includes: King Nikola’s Museum, the Museum of Petar II Petrovic Njegoš, the birth house of Njegoš, the Njegoš Mausoleum on Lovćen, Bishop Danilo’s Mausoleum on Orlov Krš, the Art Museum together with the Dado Đurić Contemporary Art Gallery, the Ethnographic Museum and the newly-opened Archaeological Museum and Lapidarium. The National Museum houses collections of weapons, medals, flags, crests, stamps, photographs, as well as archaeological, numismatic, ethnographic and applied art collections. There are also the residence and the chapel raised in honour of the secular and spiritual leader, poet and philosopher Petar II Petrović Njegoš. During the 1970s the Montenegro Art Museum was known as the Art Gallery, and houses some 3,000 exhibits, including some of the most important works in contemporary Yugoslav and Montenegrin fine art.
