Chęciny Royal Castle was built in the late 13th century in Chęciny, Poland. It fell into ruin in the 18th century and remains in that state to this day.
In the second half of the 16th century, the castle began to decline. In 1588 the parliament ordered to transfer the castle's inventories to the Chęciny Church and in 1607, during the Zebrzydowski Rebellion the fortifications and buildings were partially destroyed and burned.[3] The castle briefly regained its former glory due to reconstruction initiated by Stanisław Branicki, starost of Chęciny, but in 1655-1657 it was almost completely destroyed by Swedish-Brandenburgian and Transylvanian troops.[3] The destruction was completed in 1707 during another Swedish occupation.[1] Then, the last residents left the castle. Over the next century the medieval walls become a source of building material for local villagers.[3]
