Eltz Manor is a Baroque palace in Vukovar, Croatia. The 18th-century manor is the location of the Vukovar City Museum. The manor, as it previously appeared, was depicted on the reverse of the Croatian 20 kuna banknote, issued in 1993 and 2001. The palace suffered substantial damages and destruction in 1991 during the Croatian War of Independence. However, after four years of restorations, it was completely restored to its pre-war appearance in October 2011.
