The Kavilda stronghold (Kawelecht) was, according to Leonhard von Stryk, first built in 1354 by Bartholomäus von Tiesenhausen. Other sources say it was built in 1361 by Arnold von Vietinghoff, the Master of Livonian Order. The castle was destroyed during the Livonian War somewhere between 1564 and 1582. It was probably knocked down before the invasion of the Poles. Thereinafter Kavilda excisted only as a manor but not as a castle.
The castel was a castellum-like building with a tower-shaped residential building. Nowadays only one and a half floors have remained, most of it under the ground.
References:The Château du Lude is one of the many great châteaux of the Loire Valley in France. Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
