There has been a castle or stronghold in Johannesberg since the 11th century. The hill surrounded by water has been easy to defend. During the 12th century a chief named Gutti lived here and the whole area became Gutti´s area, later on Gottröra, which is the name of the place today. Gutti divided the area into two parts, the south and the north. The south part – presently Johannesberg – was called Djursby.
The owner of Djursby during the later part of the 17th century was Johan Leijonhufvud. He gave the estate to a close relative, Adam Lewenhaupt, who named it Johannesberg after Johan Leijonhufvud. Lewenhaupt died in Russian captivity and was never to see Johannesberg again. After Lewenhaupt the estate was owned by different nobility families – Banér, Gyllenstierna, Horn af Åminne and Lagergren. At the end of the 19th century Johannesberg was taken over by a Mr Grönwall, a wholesale dealer. During his time the main building unfortunately burnt down. The next owner, Mr Conti, built the present mail building around the turn of the century.
The estate was bought in 1930’s by Bergengren, who at the end of the decade owned many estates in Sweden, England and France. Bergengren is still the owner of the agricultural part of Johannesberg.
During World War II Bergengren rented out the main building and several crofters cottages to the Swedish government and under the management of the manager for the Criminal Technical Institution, Harry Söderman, Norwegian refugees were here officially beeing educated to police men. In fact they were educated to join the resistance movement. At the maximum there were about 1500 Norwegians here for education. Many of them have through comrade clubs kept in touch with each other after their return to Norway. They have collected money and this resulted in a monument beeing raised in the castle park at Johannesberg in June 1990.
In 1987 Johannesberg was bought by a private company. It was restored, the two wings were built ant the estate was ready to take into use in the springtime 1989. The golf course with 27 holes was set up and opened in 1991. A club house with swimming pool was ready at the same time. The castle is owned and operated since 1995 by the family Manfred and Mariette Kuhl.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
