The Bip Castle was constructed in 1795-1797 under the project of architect V. F. Brenna by the order of emperor Paul I. There were remains of old sweden fortification on the place of construction. This place is rather convenient for such kind of buildings. The Castle was included in the military register of fortresses of the Russian Empire and there was small garrison under command of commandant Arakcheev. The drawbridge was lifted at the sunset and gun fired a shot on midday.
After Paul's I death various institutions had accommodation here such as the School for deaf children, Clinic of cavalry regiment, Aleksandrovskij college, Pavlovsk city board. After October 1917 coup d’etat there were orphaned house, military komissariat, sovdep(local council of 'peoples' deputies). During WWII the Bip Castle has burned down, but today it is restored as a hotel.References:
Varberg Fortress was built in 1287-1300 by count Jacob Nielsen as protection against his Danish king, who had declared him an outlaw after the murder of King Eric V of Denmark. Jacob had close connections with king Eric II of Norway and as a result got substantial Norwegian assistance with the construction. The fortress, as well as half the county, became Norwegian in 1305.
King Eric's grand daughter, Ingeborg Håkansdotter, inherited the area from her father, King Haakon V of Norway. She and her husband, Eric, Duke of Södermanland, established a semi-independent state out of their Norwegian, Swedish and Danish counties until the death of Erik. They spent considerable time at the fortress. Their son, King Magnus IV of Sweden (Magnus VII of Norway), spent much time at the fortress as well.
The fortress was augmented during the late 16th and early 17th century on order by King Christian IV of Denmark. However, after the Treaty of Brömsebro in 1645 the fortress became Swedish. It was used as a military installation until 1830 and as a prison from the end of the 17th Century until 1931.
It is currently used as a museum and bed and breakfast as well as private accommodation. The moat of the fortress is said to be inhabited by a small lake monster. In August 2006, a couple of witnesses claimed to have seen the monster emerge from the dark water and devour a duck. The creature is described as brown, hairless and with a 40 cm long tail.
