Dominating the square is the Renaissance-style church and Morosini-Grimani castle, both built in the 13th century (the castle's towers were added later in the 16th century). There's also an enclosed well taking up a section of the square and in the south-western corner, a loggia.
This atmospheric Renaissance piazza and the castle provide the backdrops for the annual medieval festival held here in the summer, and a contemporary dance festival every July.
On a summer evening, Svetvinčenat is a great place to have a drink at one of the little cafes lining the road leading to the square, or a pizza on the terrace right on the square itself.
The arched windows of its houses, crumbling facades and antique-style lanterns also add a touch of old world charm that make this little town one of my favourites in Istria.
