Alytus mound is the only preserved witness of the foundation of the town and it dates probaly from the 11th century. It is said that a wooden castle was standing here in the 14th century that was burnt down later by the Teutonic Order. The detailed route to Alytus castle is described in Teutonic “The Description of Lithuanian Roads”, this castle defended the main roads to Trakai and Vilnius from crusaders.
An impressive panorama of the town opens from the mound, while its foot is decorated by an exposition of sculptures “Ancestors of Alytus Mound”.
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.
