Porkuni (German: Borckholm) is a village in Tapa Parish, Lääne-Viru County, in northern Estonia.[1] The settlement is located around the Lake Porkuni, which is the source of the Valgejõgi River.
In 1944, the Battle of Porkuni was fought in the area.
In 1479, a castle was built on an island in the lake by the bishop of Tallinn Simon von der Borch. Porkuni castle (German: Schloss Borkholm) was a four-sided structure surrounding a central courtyard, where a small church stood. In each corner of the castle stood a cannon-tower, and there was also a gate tower which is still preserved, albeit with a few later alterations. Judging from the remains, the castle was built in different stages and the walls were gradually made higher.[2]
The castle was destroyed during the Livonian War.
In 1870–74, a new manor house was built at the site by the landowner at the time, Otto Ludwig von Rennenkampff. Perhaps not surprisingly, it is built in a neo-Gothic style, with turrets and other details inspired by a romantic perception of the Middle Ages. The ceremonial rooms of the manor, on the first floor, have been restored. The interior also houses a wrought iron staircase and a noteworthy art nouveau cocklestove.[3] [4] The manor house and grounds is now owned by UK telecommunications operator aql.[5]
