While a scheduled monument can also be recognised as a listed building, English Heritage considers listed building status as a better way of protecting buildings than scheduled monument status. If a monument is considered by English Heritage to "no longer merit scheduling" it can be rescheduled.[2]
Derbyshire has over 500 scheduled monuments including many stone cairns, stone circles, barrow burial mounds, lead mining relics, ancient settlements, and over 20 bridges.[3]
A medieval castle built on the site of an earlier royal manor house in the reign of King John. Construction of the castle was started in 1311 and continued until 1322, but the work was never fully completed. Also a Grade II listed building.[16]
