Ventlinge Church, dedicated to St. Lawrence, was built during the first half of the 1100's. It began as a towerless vestibule church of Romanesque style. Around the year 1200, a defensive tower entirely on its own grounds was added. Above the staircase entrance in the porch is a throw shaft straight up through the wall. Church defenders could also stand on the tower’s second floor and throw stones at unwelcome visitors. In 1812, the church was repaired and rebuilt so its medieval character was lost. The lantern was added to the tower in 1825.References:
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.
