Without those Chantry Closes next to the Bridge leading into Buckingham Parish, are two remarkable Tumuli, which I judge were raised in the Time when the Romans possessed this Island, on Account of some Battle fought here. The Vulgar have several odd traditions about their being inhabited by Fairies, &c.
From the chapter on Thornborough, in ‘The history and antiquities of the town, hundred, and deanry of Buckingham’ by Browne Willis, 1755.
