A series of secret rooms and a tunnel have been discovered under a building in Loughborough. The secret living quarters belonged to John Heathcote, a man who invited the fury of the Luddites after inventing a lace-making machine in the early 1800s.
. . .
Keeper of Charnwood Museum Susan Cooke added: "We don’t know if (John Heathcote) did actually hide down there because he fled Loughborough and went to Devon."
. . .
Activists smashed Heathcote’s lacemaking machine in Loughborough in 1816.
