Gammelstad Church Town is a UNESCO World Heritage Site situated in Gammelstaden near the city of Luleå. It is the best preserved example of a type of town that was once widespread throughout northern Scandinavia. As Church Village of Gammelstad, Luleå, it was listed as a World Heritage Site in 1996. At its centre is an early 15th century stone church surrounded by 424 wood-built houses. The houses were only used on Sundays and during religious festivals to accommodate worshippers from the surrounding countryside who could not return home the same day because of the distance and difficult travelling conditions.
The church in Gammelstad is the biggest medieval church in Northern Sweden. It was built in the 15th century, and according to tradition it was inaugurated by Archbishop Jacob Ulfsson in 1492. The whitewashed bell tower was built in 1851.The interior is richly ornamented and furnished. The late-medieval frescoes in the chancel are by the School of Albertus Pictor. They were whitewashed over in the 18th century but restored in 1909. To the right of the altar there are medieval pews and a reconstructed bishop´s throne or cathedra. The triptych above the altar was built in Antwerp in around 1520 and cost 900 silver marks, and enormous sum which the farmers of Luleå are said to have paid in cash. The pulpit and memorial tablets were made by Nils Jacobsson Fluur at the beginning of the 18th century.
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.
