Walburg Castle dates from the 16th century. In 1553 knight Willem van Waelwijck built his moated castle within walking distance of the market. He named his castle after his wife, Walburgis. The former domain consisted of an orchard, a garden and two country roads. The castle changed hands several times and, among other things, it was turned into a brewery in 1618. In the 19th century it came into the hands of the Van Naemen family and the castle was renovated. The park was also converted into an English garden.
The castle was acquired by the municipality in 1949. The park was opened to the public in 1952. After the death of the mayor Romain De Vidts, the park was renamed Romain De Vidtspark.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
