The building of St. Michael’s church in Kihelkonna was probably started in the mid-13th century and completed between 1270-1290. In the early Middle Ages Kihelkonna was one of the most important centers in Saaremaa. It was situated on the road connecting the western part of Saaremaa with mainland Estonia. There was also a harbor of considerable importance here. Both the Bishop and the Livonian Order contributed to the construction of the church, which was begun in the middle of the 13th century. Initially, a fortified western tower, as wide as the nave, had been planned but its construction was interrupted, apparently in its early stages, by the revolt of 1260-1261.
Inside the church the altarpiece (1591) and the pulpit (1604) are among the oldest of their kind in Estonia. Also worthy of mention is the organ, which was made in 1805 by J.A. Stein. It was reconstructed in 1890 by F. Weisseborn from Jekabpils in Latvia.
South of the church is located a distinct bell tower - so-called campanile. This stone-made, free standing bell tower was built in 1638 and is the only one remaining in Estonia. The tradition of such bell towers became widespread in Estonia in the 17th and 18th centuries.
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.
