The former castle in Navahrudak, Belarus (Belarusian: Навагрудскі замак, Lithuanian: Naugarduko pilis, Polish: Zamek w Nowogródku) was one of the strongholds of the Grand Duchy of Lithuania, cited by Maciej Stryjkowski as the location of Mindaugas's coronation as King of Lithuania as well as his likely burial place. On the opinion of Lithuanian historians (T.Baranauskas etc.), there is no information that King Mindaugas lived or visited Navahrudak at all - it is Maciej Stryjkowski's 16th century written conjecture in the interpretation of legends. As early as the 14th century, the Principality of Navahrudak is known to have possessed a stone tower along the lines of Tower of Kamyanyets. Other fortifications were made of timber. The castle was stormed by the Teutonic Knights under Heinrich von Plötzke in 1314. Although the attack was not successful, the tower sustained substantial damage. During the reign of Vytautas the Great four new stone towers were added to the system of Navahrudak fortifications. In the 17th century, the main castle boasted 7 towers, apart from those of the Lesser Castle.
