Pleven, historically known in English as Plevna, is the seventh most populous city in Bulgaria. Located in the northern part of the country, it is the administrative centre of Pleven Province, as well as of the subordinate Pleven municipality. Internationally known for the Siege of Pleven of 1877, it is today a major economic centre of the Bulgarian Northwest and Central North and the third largest city of Northern Bulgaria after Varna and Rousse. Pleven is located in an agricultural region in the very heart of the Danubian Plain, the historical region of Moesia, surrounded by low limestone hills, the Pleven Heights. The city's central location in Northern Bulgaria defines its importance as a big administrative, economic, political, cultural and transport centre. Pleven is located 170 km away from the capital city of Sofia, 320 km west of the Bulgarian Black Sea Coast and 50 km south of the Danube. The river Vit flows near the town and the tiny Tuchenitsa river (commonly known in Pleven as Barata, literally "The Streamlet") crosses it. Most of the sights of the town are related to the Russo-Turkish War. The monuments related to the war alone are about 200. Some of the more popular include the St George the Conqueror Chapel Mausoleum in honour of the many Russian and Romanian soldiers who lost their lives during the Siege of Pleven and the ossuary in Skobelev Park. Another popular attraction is Pleven Panorama, created after (and reputedly larger than) the Borodino Panorama in Russia on the occasion of the anniversary of the Siege of Pleven. The Pleven Regional Historical Museum is another popular tourist attraction, while the Svetlin Rusev Donative Exhibition, situated in the former public baths, exhibits works by Bulgarian artists, as well as noted Western European art figures like Pablo Picasso, Francisco Goya, Honoré Daumier, Marc Chagall, Maurice Denis, Pierre-Auguste Renoir, Salvador Dalí, Renato Guttuso and Eugène Delacroix, Auguste Rodin and Edgar Degas.
