There are about 40 000 barrows known in Britain, so they are not normally excavated. You'd think if you had a barrow in your neighbourhood you'd want the archaeologists down there sharpish to find the vast hoards of torques, gold coins, and skeletons of horses you would hope were in there. Or at least to see some incautious student devoured by a barrow-wight.

A place name ending in -howe is likely to indicate a barrow. A place like Nickerhowe is more or less guaranteed to have had a resident wight, at least in the balmy days when wights flourished.

One of the best is at West Kennet in Wiltshire.
