The Morosini-Grimani Castle is the symbol of Svetvinčenat (Sanvincenti) and one of the best-preserved Renaissance fortresses in Istria. Its origins date back to the 13th century, when the De Castro Pola family built their first fortified residence there. Passed to the Morosini family in the 15th century, it was transformed into a true fortress and, after a devastating fire in 1586, rebuilt in Renaissance style by the Grimani family with the help of Venetian architects. The quadrangular structure with three towers and an elegant noble palace combined defensive, administrative, and economic functions: grain storage, armory, and the captain's residence. Topped by the Grimani coat of arms, which later became the emblem of the city, the castle endured centuries of wars, fires, and dominations, until it was once again destroyed in the Second World War. Today, after careful restoration, the castle has come back to life: it hosts exhibitions, events, and multimedia tours that allow visitors to discover the history of Svetvinčenat and one of the most fascinating Istrian fortresses.

Impressive complex from the time of the k&k monarchy - unfortunately no opening hours can be found - just drive there.

At the foot of the northern ramparts of Pazin Castle there is an extremely valuable sequence of residential buildings in the late Gothic and Renaissance styles. These were the houses of the officials of the Pazin and Istria County who performed their duties within the castle itself, and therefore these buildings should be considered an integral part of Pazin Castle and treated accordingly. These buildings were built within the former walled suburb of the castle, and the remains of the ramparts are hidden within the structures of the eastern row of buildings. The architectural elements visible today were mostly built in the 16th century, but closer analysis would certainly reveal older structures given the earlier construction of the suburban ramparts. Some of the buildings were also rebuilt several times in later centuries.

A dilapidated chapel in which many votive pebbles are still deposited. Behind the chapel you have a great view of the sea at Rabac

Beautiful little town with a nice castle in the middle. Museum in the castle (for a fee). Very nice. There are a few cafes around the castle where you can relax.
