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:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
