Associated with the Jenny Bradley Cross near to Bloworth Crossing on Stockdale Moor, is the Margery Bradley Wayside and Boundary Stone, a Grade II Scheduled Monument. This Stone is positioned at the side of Blakey Road opposite to Rosedale Head. The Margery Stone is only 200m east north east of Flat Howe. The Lion Inn is less than a mile south along the Blakey Road.

The Margery Bradley Stone has been located in its current position since medieval times, but it is thought that it originated during the Bronze Age and may be associated with the nearby Flat Howe Round Barrow.

The Margery Bradley Stone was once named "Breadless" and was a place where beggars gathered to seek alms. The same goes for the Jenny Bradley Cross, often referred to as the sister stone to the Margery Bradley Stone for the same reason.

The Stone was regarded as an important marker when the Beaker Folk from mid and eastern Europe settled in the area about 4,500 years ago, i.e. during the Bronze Age. They derived their name from their unique bell-shaped pottery, mostly used as drinking vessels and having an elegant flared lip. They also introduced the custom of burying their dead in raised earthern burial mounds.
