Czersk is a small township, 39 km from the center of Warsaw.
This medieval brick castle was built on a hill between 1398 and 1406 for the Mazovia Prince - Janusz I Starszy. It had three towers and curtains which were 8 meters high and almost 2 meters thick. Czersk became the capital of the Mazovian Duchy due to its significant settlement along the Vistula river. Queen Bona Sforza, among others, lived in the castle.
In the 15th century, however, the Vistula river shifted its bed, moving away from Czersk. As a consequence the site fell into obscurity and the castle began to decay.
During the Swedish invasion in 1655–1660 the castle was nearly destroyed. Briefly rebuilt in 17662–1766.
Today the castle ruins and the pituresque village have become tourist attractions. The towers were recently renovated and there is a fantastic view of the Vistula River valley from their terraces.
