Parcul Carol I
Tatars in Tulcea County were driven out by Russian troops during the Russo-Turkish War of 1877–1878 ("see Muhajir Balkan"). Following the conflict and the Berlin Congress, the Romanian government of Ion Brătianu agreed to extend civil rights to non-Christians. In 1923 a monument in the shape of a small mosque was built in Bucharest's Carol Park, as sign of reconciliation after World War I. A small Muslim community resided on Ada Kaleh island in the Danube, south of the Banat, an Ottoman enclave and later part of Austria-Hungary, which was transferred to Romania in 1923.
