The medieval stone church of Ås date back to the 12th century. It is the only church in Öland where the tower is located in the east side. The church was enlarged in 1770 and the interior is mainly from the 18th-19th centuries. The pulpit is very unusual; this nineteenth century work is directly above the altar, an arrangement rarely seen in Swedish churches. The church is long established as a landmark for seafarers. During the nineteenth century the tower was rebuilt to incorporate a lantern, so that it doubled as an early lighthouse.References:
Bouillon Castle was mentioned first in 988, but there has been a castle on the same site for a much longer time. The castle is situated on a rocky spur of land within a sharp bend of the Semois River.
In 1082, Bouillon Castle was inherited by Godfrey of Bouillon, who sold it to Otbert, Bishop of Liège in order to finance the First Crusade. The castle was later fitted for heavy artillery by Vauban, Louis XIV's military architect in the late 17th century.
The castle is entered over three drawbridges. The main courtyard then leads to the ducal palace with its 13th century Salle Godefroy de Bouillon. From there visitors climb up to the top of the 16th century Tour d’Autriche for a breathtaking panorama of the town and river, before they way back via the torture chamber, citerns and dungeons, and past the 65m deep well Shaft.
