Bentley is noted for its involvement in the English civil war, when in 1651 King Charles II took shelter with the Lane Family in Bentley Hall while attempting to escape to exile.
In addition to these improvements, the remains of another manor house near the Cairn were discovered during May 2006, and an archaeological survey will take place by the Bentley Cairn Restoration Group, funded by the Darlaston Local Neighbourhood Partnership, in order to confirm and restore the remains of the house.
