This is one of those unusual mounds that are not scheduled ancient monuments, yet have been treated kindly by the modern landowners. OS says Tumulus in that alluring typeface but then they have been known to get it wrong. There is not much to see but a bump of about 50cm height in some rough pasture. It is all quite horsey round here so hopefully will not deteriorate further for future generations. I wonder whether it was ever very big or one of the smaller late bronze age efforts.
