[1] The castle hill has been used since at least 400 AD, based on Roman artifacts found there.

The site of the neighboring chapel has been used for religious ceremonies since the Roman era.

During the 8th century the chapel site was used by a "holy bishop without a name" for Christian services.

Today the castle and chapel are located on a 67,000 square metres (720,000 sq ft) private park.

While the castle is privately owned, the grounds are opened to the public twice a year.
