Pietrapelosa is a castle in the Croatian part of Istria, now ruined. In the medieval period a family took their name from the castle.
"Pietrapelosa" comes from the Italian words meaning "hairy stone" after the moss that has always grown on the walls of the castle.
It is one of the best-preserved of the Istrian castles.
