Pietrapelosa

Pietrapelosa, also known locally as Kostel or Kosmati grad, is a historic castle situated in the Croatian part of Istria, just a few kilometers west of the town of Buzet. Perched strategically at the head of the Bračana valley, the fortress offers dramatic views of Northern Istria. First documented in 965 AD when it was gifted by the Patriarch of Aquileia to the bishopric of Poreč, the site has served as a crucial administrative center for centuries. Its name, derived from Italian words meaning hairy stone, references the moss that traditionally covered its walls. The structure is notable for being one of the best-preserved castles in the region, having remarkably avoided destruction during the many wars that ravaged Istria throughout history.

The architectural complex originally featured three-story surrounding walls that remain intact today, along with a main four-story polygonal watchtower that doubled as a residence. A palace chapel dedicated to St. Mary Magdalene, dating back to the 12th century and built in the classic Istrian style with a single nave and bell tower, was also part of the estate. Historically, the castle served as the seat for the Aquileian lieutenant governor before passing to German knights in the 13th century who adopted the castle's name. In 1421, Venetian forces conquered the site, and by 1440, it was granted to the nobleman Nicolò Gravisi, who renovated it into a summer residence. Although a fire in 1635 destroyed the interior, the building was restored and inhabited by the Gravis family until the abolition of the feudal system in 1869.

After falling into ruin following its abandonment in the late 19th century, Pietrapelosa has recently undergone restoration efforts. While the interior suffered damage from the historical fire and subsequent neglect, the external walls and tower structure have survived largely intact. Today, the site stands as a significant cultural landmark representing medieval military architecture and the complex feudal history of the Istrian peninsula. It remains a testament to the region's layered past, transitioning from a strategic military outpost and governor's seat to a noble summer retreat, and finally to a preserved historical ruin accessible to visitors interested in the heritage of Croatia.
