In 1925, a confusion by the scholar Nándor Fettich misplaced the important Magyar burial site discovered at Cheglevici into the Orșova region. Later, the location of that discovery, testifying to the presence of the Magyars since the early 10th century, was clarified for the archeological community.
During the works at the Iron Gates, the old center of the town was flooded and Orșova was developed (1966–1971) on higher ground, including the southern side of the Almăj Mountains and the villages of Jupalnic, Tufari, and Coramnic. Also flooded then was the neighboring Ada Kaleh, with the scattering of the mostly Turkish community of the Danube island. Ada Kaleh and its inhabitants, as well as the ancient city, are still present in the memory of its surviving locals.
The Orșova shipyard was constructed in 1890 and like a small reparation shop for the vessels which participated to the navigable channel from Iron Gate Romania- Sip Yugoslavia and had a continuously development along time. After the year 1991 the name was changed and also the organizational profile.
A wind farm is being developed in the city territory, on a hill nearby (at 4.5 km from the agglomeration); the first turbines became active there in 2009.
