The medieval church of St. Clemens in Sauvo was built to present three-aisle outfit probably in 1460s or 1470s. First record of the Sauvo Church in Turku Cathedral documents dates back to the year 1346, but there have been several wooden churches before even from the beginning of 13th century.
Many renovations were made to the church during 17th century, but the interior is very well-preserved. Mural paintings are from the 15th century and there are several medieval artefacts, like an altar, triumph crucifix and tabernacle.
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.
