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.
Sirmione castle was built near the end of the 12th century as part of a defensive network surrounding Verona. The castle was maintained and extended first as part of the Veronese protection against their rivals in Milan and later under the control of the Venetian inland empire. The massive fortress is totally surrounded by water and has an inner porch which houses a Roman and Medieval lapidary. From the drawbridge, a staircase leads to the walkways above the walls, providing a marvellous view of the harbour that once sheltered the Scaliger fleet. The doors were fitted with a variety of locking systems, including a drawbridge for horses, carriages and pedestrians, a metal grate and, more recently, double hinged doors. Venice conquered Sirmione in 1405, immediately adopting provisions to render the fortress even more secure, fortifying its outer walls and widening the harbour.
Thanks to its strategical geographical location as a border outpost, Sirmione became a crucial defence and control garrison for the ruling nobles, retaining this function until the 16th century, when its role was taken up by Peschiera del Garda.
