Located just beside the Lion Inn on the Castleton to Hutton -le-Hole road.
Blakey Howe is easily mistaken for one of the many mine workings that cover High Blakey Moor.
If you check it out you will find a dug-out round barrow topped with a boundary stone.
The usual boundary stones for this area are about .5m tall, rectangular and fairly uniform. This fella is 1.5m tall and doesn't look like any of the other stones.
The carved letters on the side proclaim the boundary of whoever owned the moor (and probably still does) but the stone implies a greater antiquity.
Whilst your there call in at the Lion Inn, great beer & decent grub.
There are excellent views across Rosedale to the Victorian Ironstone workings and the calcining kilns.
