Oryahovo (Оряхово) is a port city in northwestern Bulgaria, part of Vratsa Province. It is located in a hilly country on the right bank of the Danube, just east of the mouth of the river Ogosta, a few more kilometres downstream from where the Jiu flows into the Danube on Romanian territory. The town is known for the ferry service that connects it to the Romanian town of Bechet across the river. There are also plans by local private companies for a bridge across the Danube.
During the Bulgarian National Revival, Oryahovo established itself as an economic and indsutrial centre and a key point for the supply of the Ottoman Empire with goods through the Danube. The town was mentioned as an important Danube port in a 1762 book printed in Brussels. The St George Church was opened in 1837, a secular school was built in the town in 1857 and a community centre (читалище, chitalishte) followed in 1871. During the Russo-Turkish War of 1877-78, the town was liberated on 21 November 1877 by Romanian forces after three-day fighting. A memorial by Italian sculptor Arnaldo Zocchi was erected in their honour.
A railway line linking Oryahovo with Cherven Bryag was constructed in 1926, a new church, the Assumption of Mary Church, opened in 1930, and a new building for the community centre was built in 1936 after a project by two Vidin architects.
Some of the first industrial companies in the city, a spare parts factory and a metalworking company, were opened in 1961. Kozloduy Nuclear Power Plant, a short drive west of town, is also a mayor employer.
