- In 1925, a confusion done by scholar Nandor 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.
- It was a major border fortification in the Middle Ages.
- The city was captured by Suleiman the Magnificent in 1522.
- Orșova became part of the Habsburg Monarchy in 1687 at the start of an Ottoman-Habsburg War, but Ottoman forces recaptured it in 1690. The Treaty of Passarowitz gave the city back to the Kingdom of Hungary in 1718. Treaty of Belgrade gave the city back to the Ottoman Empire in 1739. Finally, The Treaty of Sistova gave the city back to the Kingdom of Hungary in 1791. The city remained in Hungary until the end of World War I, when it became part of Romania. It was included in the Mehedinți county during the administrative reform of 1968.
- The Hungarian Crown of Saint Stephen was buried near Orșova from 1848 till 1853.
- 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.
