Kufstein fortress is one of the most impressive medieval constructions in Tyrol. It is located on a hill rising above the city of Kufstein. This fortress has already been built very early in order to control the entrance from the Alpine foothills into the Inntal valley. However, it has been mentioned for the first time in 1205 AD, when it was in possession of the bishops of Regensburg. In 1415 it was reinforced by Louis VII, Duke of Bavaria.
In 1504 the city and the fortress were besieged and conquered by Emperor Maximilian I. Maximilian had the massive round tower built between 1518 and 1522, substantially adding to its defensibility. From 1703 to 1805 it was a Bavarian possession, returning to Austria in 1814. The fortress acted as prison for a number of political dissidents during the Austro-Hungarian empire.
Today it houses the City Museum of Kufstein. Part of it is also used for concerts and meetings.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.
