The current Węgorzewo town was first mentioned in a 1335 chronicle as Angirburg, or 'eel castle', a settlement of the Teutonic Knights with a block house, a palisade, and a watchtower. The Grand Duke of Lithuania, Kęstutis, destroyed the wooden castle in 1365. Teutonic Knights built new brick castle in 1398. It was situated 2 km away from burnt castle on river island. Near by the castle grew settlement New Village which got allocation privilege in 1514.
From 1525 the castle was a residence of princely district. In 1734 and 1736 King of Poland Stanislaw Leszczynski visited the castle. After World War II the town was burnt by Russian soldiers and the castle was destroyed. It was rebuilt in 1980's.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.
