The Mansfield Museum in Leeming Street holds archaeological material. This includes a sculptured corbel and voussoir fragment from excavations at Kings Clipstone.

At Kings Clipstone, a village 5 miles NE of Mansfield, from where the fragments come, are the ruined walls of a former medieval royal residence previously used for hunting trips into nearby Sherwood Forest. While there is no conclusive proof of the medieval royal residence being built by King John there were known to be 1400 acres of forested deer park (and 70 acres of rabbit warrens) next to the village, which were used by royal hunting parties. It became a large palace complex under the Plantagenet Kings.

Excavations were carried out in 1956 and 2012 at the site.

Both carved stones from the site, excavated at an unknown date, appear to be 12thc. They imply the presence of a reasonably substantial building with a sculptured Romanesque doorway or arch.
