Near the place where the Kilmiņupe River flows into the sea is the legendary Trommel castle hill, which was a Medieval fortification. It is some 100 m from the Kraujas homestead. An archaeological dig in 1977 found fragments of bricks and pot-bellied stoves, which suggests that the fortifications date back to the Middle Ages. The location also is linked to stories about a pirate, Trommel, who buried his loot here. The holes in the area have been left behind by treasure hunters. Trommel supposedly robbed ships in the Bay of Rīga from the shores of Kurzeme to Roņu Island. Many ships docked here in ancient times, waiting for better winds so that they could pass by Cape Kolka. The pirate made use of this fact, also pillaging property from sunken ships. It is said that Trommel lived in a stone castle. (Source: Roja TIC)
