The easternmost town in Croatia, Ilok's teensy medieval town is a leafy place perched on a hill overlooking the Danube and the Serbian region of Vojvodina, across the river. It's part of the Srijem region of Croatia, together with Vukovar, 37km to the west. Surrounded by the wine-growing hills of Fruška Gora, famous for viniculture since Roman times, Ilok has managed to cling on to a couple of grand chunks of its once sturdy city walls, its well-preserved Odescalchi Palace (now the city museum) and two rare specimens of Ottoman heritage: a 16th-century hammam and a turbe (grave) of a Turkish nobleman.
Occupied by Serbia in the early 1990s, Ilok was reintegrated into Croatia in 1998. Wine production has since been revived – the area now has 20 wineries you can tour – and the fortified town centre is being renovated following recent archaeological excavations.
