The construction of Paide order castle was started in 1265 under the leadership of Konrad von Mandern. The original tower of Tall Hermann was octagonal with the height of over 30 meters and the thickness of the walls of about 3 meters.
At the beginning of the Livonian War the Russians repeatedly besieged Paide, but only in 1573 they finally managed to invade Paide. After that it changed hands several times until the Swedes got it in 1608. In 1638 they removed Paide from the list of castles.
The rampart tower and castle ruins were first conserved at the end of 19th century. In 1913 a park was planted on the hill. In 1941 Soviet soldiers destroyed the rampart tower, the symbol of both Paide and Järva County. To celebrate the 650th anniversary of the St. George's Night uprising the tower was restored in 1993. Today it houses a museum.
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.
