Ruse (also transliterated as Rousse, Russe; Bulgarian: Русе [ˈrusɛ]) is the sixth-largest city in Bulgaria. Ruse is in the northeastern part of the country, on the right bank of the Danube, opposite the Romanian city of Giurgiu, approximately 67 km (42 mi) south of Bucharest, Romania's capital, 172 km (107 mi) from Varna, and 249 km (155 mi) from the capital Sofia. Thanks to its location and its railway and road bridge over the Danube (Danube Bridge), it is the most significant Bulgarian river port, serving an important part of the international trade of the country. It is the 12th-largest of all cities on the river Danube.
Ruse is known for its 19th- and 20th-century Neo-Baroque and Neo-Rococo architecture, which attracts many tourists. It is often called the Little Vienna. The Ruse-Giurgiu Friendship Bridge, until 14 June 2013 the only one in the shared Bulgarian-Romanian section of the Danube, crosses the river here.
