Rousse (also transliterated as Ruse or Russe; Bulgarian: Русе ['ru.sɛ]) is the fifth-largest city in Bulgaria, with a population of 175,632. Rousse is situated in the northeastern part of the country, on the right bank of the Danube, opposite the Romanian city of Giurgiu, 300 km from the capital Sofia and 200 km from the Bulgarian Black Sea Coast. It is the most significant Bulgarian river port, serving an important part of the international trade of the country. Rousse is known for its 19th- and 20th-century Neo-Baroque and Neo-Rococo architecture, which attracts many tourists. The Rousse-Giurgiu Friendship Bridge, the only one in the shared Bulgarian-Romanian section of the Danube, crosses the river nearby.
