Pietrapelosa: the moss-covered castle above the Bračana valley
Pietrapelosa (locally Kostel) is a castle ruin on a high crag a few kilometres west of Buzet, in the Croatian part of Istria. It stands at the head of the Bračana valley and still has its three-storey walls and the outline of its watchtower. Few visitors come this way, and the view over northern Istria rewards the effort of finding it.
Pietrapelosa means “hairy stone”, a name it earned from the moss that has always grown on its walls. Perched on a crag in northern Istria, it is one of the best-preserved castles of the peninsula.
The history of Pietrapelosa
The crag was lived on long before the castle existed. Fragments of Bronze Age and Iron Age pottery have been found here, along with a hoard of iron weapons dated to around 600 BC, and the terraces of a prehistoric hillfort can still be recognised on the north side. A Roman fortified post is also believed to have stood on the rock, although archaeological research has not fully confirmed every theory about the earliest fort.
Little is known about the site between the 8th and 11th centuries. The Franks took over Istria at the end of the 8th century and brought the feudal system with them, and German families became the lords of the fortified castles they built. One account suggests that the medieval fortress was raised on the remains of the prehistoric hillfort.
The castle first appears in writing in a document of 965, in which Rodaold, patriarch of Aquileia, gave it to the bishopric of Poreč. According to the Croatian sources, the deed names a stronghold called Ruvin, from the Latin word for ruins, and this name later gave the German Rauenstein, which was then translated literally as Petra Pilosa. In the 13th century the castle passed to a family of German knights who took its name and became the “de Pietrapelosa”. In 1208 the patriarchs granted it to their vassal Vulginius de Petrapilosa, whose descendants held it until the death of the last of the family, Nicolò, in 1352. It was also the seat of the lieutenant governor of Istria for the patriarchs of Aquileia.
In 1421 the Venetian commander Taddeo d'Este conquered the castle and ended the secular rule of the patriarchs of Aquileia, and Istria was divided between the Republic of Venice and the Habsburg County of Pazin. In 1440 the Venetian Council of Ten granted Pietrapelosa to the nobleman Nicolò Gravisi, with the title of Marquis of Pietrapelosa. He renovated the castle and used it as a summer residence.
A fire in 1635 destroyed the interior, but the castle was restored and stayed inhabited, mostly by soldiers and occasionally by nobles, until the 18th century. The chapel of St Mary Magdalene held its last service in 1793. The Gravisi family kept it until the final abolition of the feudal system in 1869 and were the only aristocratic family of Koper to own such an estate. After the castle was abandoned it fell into ruin; it has only recently been restored.
