You'll only see one round barrow here, and it's quite sizeable, being 3.5m high. But there was actually another 25m to the east, which was lost by ploughing. I wonder what twist of fate led to one gaining itself a name, and the other disappearing. Can the 'Ickle' be to do with the 'Icknield' Way, which is close by? But it's on a hill so I don't know where the 'ford' must be from.
Some excavations were made in 1816, when a cremation burial was found, along with two bronze spear heads and a copper blade. A skeleton was also found in or near the mound - perhaps this was from a later era?
The barrow is not far from Wilbury Hill and the Icknield Way. You can probably see it quite well from the train between Hitchin and Letchworth.
