The castle was built in a relatively short time and has dominated Woerden's city center ever since. The first mention dates from 1415 and can be found on a drawing for the castle's construction. Based on this document, it is assumed that construction began in 1410. Steward Heynric Hermans is considered the first resident. He was an innkeeper and represented the Duke of Brabant, Jan van Beieren, who built the castle in Woerden. Even then, the castle served as a safe haven for the Duke's guests.
The towers are connected by stone-vaulted corridors. At the end of the 15th century, it was used as the official residence of the Bailiff of the Land of Woerden. It retained this function until the end of the 18th century. In the 19th century, it served as a prison for men for a time, and later for women. Afterward, it served as a central warehouse for military supplies, a function the castle retained until the early 1980s.
Now, more than 600 years later, Woerden Castle is known as the premier event venue in the Groene Hart region and serves as a safe haven for all its guests.
