'Wolf's Valley') in Croatia, is an archeological site, an elevated ground on the right bank of the River Danube, which also forms the border with Serbia.

It is estimated that the site had once been home to about 3,000 inhabitants, making it one of the largest and most important European centers of its time.

Due to extremely favourable strategic position, Vučedol has always been open to colonization.

Some of the most important archaeological discoveries belonging to the Vučedol culture have been made at this site.
