evidence: Island of Šarengrad (Croatian: Šarengradska ada, Serbian Cyrillic: Шаренградска ада, pronounced [ʃǎreŋgratskaː ǎːda] or [-ǎda]) is a Danube river island situated close to the village of Šarengrad in Croatia.[1] It covers an area of 9 km2 (3.5 sq mi).[2] The old riverbed of the Danube caused problems for navigation due to its heavy bending in this area. In order to solve the problem, Austria-Hungary began digging a canal in 1892 to straighten the flow of the river. After 17 years, the Mohovo-Šarengrad canal was finally finished, and as a result the Island of Šarengrad was formed in 1909.[2][3] [...] References - ^ Šarengrad Archived 2008-04-24 at the Wayback Machine, sarengrad.info.ms; accessed 11 June 2017.
