Monkodonja is a Bronze Age hillfort on a low hill about 6 kilometres east of Rovinj, occupied continuously from around 2000 to 1200 BC. It is one of the best-preserved fortified Bronze Age settlements in the Mediterranean, with substantial dry-stone walls still standing to a significant height in places. The site was excavated by Croatian and Swiss archaeologists over two decades beginning in the 1990s.
The remains include a central citadel area, a lower town enclosed within the outer walls, and evidence of sophisticated metalworking, trade, and social organisation. Finds from the site — tools, weapons, jewellery, pottery — are displayed in the Rovinj Heritage Museum in town. Getting there requires a car or bicycle; the site itself is unguarded and freely accessible, though somewhat overgrown depending on the season. Views from the hill over the surrounding Istrian landscape are good.
