This spooky cellar is part of Rushton Triangular Lodge, a rare 3-sided building in Northamptonshire, designed and built by Sir Thomas Tresham, father of one of the Gunpowder Plotters, between 1593 and 1597. It is an English Heritage site. The cellar is unlit, and it takes a few minutes for the eyes to adjust to the gloom. To describe this building as a folly would be incorrect. Tresham was a staunch catholic, and was imprisoned for his beliefs. He built the lodge after his release and it features many symbols of his faith, both on the inside and the outside. As you can see, even the windows are 3-sided, the number 3 representing the holy trinity
