Castle of the Dukes of Masovia - Museum of the Masovian Nobility in Ciechanów

An integral part of the Museum of Mazovian Nobility in Ciechanow is the Castle of the Dukes of Mazovia, dating back to the early 14th century. It is the largest Gothic knight's stronghold in Northern Mazovia, located in a picturesque bend of the Lydynia River. Thanks to the castle's exhibitions, we learn about the medieval history of the region. The castle hosts numerous cultural events, and each year it attracts thousands of tourists from Poland and abroad. The castle was built by Siemowit III, Duke of Mazovia, in the middle of the 14th century. At the time, Mazovia was an independent principality. The castle became known throughout Poland thanks to Henryk Sienkiewicz, who described it in his novel "Teutonic Knights." It was here that the dramatic knightly duel between Zbyszek of Bogdaniec and his monastic brother Rotgier took place. The castle of the Mazovian Princes, which fell into ruins after the Swedish invasions and partitions, was rebuilt in the second half of the last century.
