Deep under the floor of the church, near the south door exists Holy Trinity’s crypt or Charnel House or even an ossuary if you prefer? This 13th century crypt lies beneath the south aisle and the nave and measures 9 metres by 4.5 meters and 2.5 metres high. It is believed to have been discovered around 1700. Local legend suggests that little was known about its existence until the day a hapless gravedigger fell into the crypt whilst working in the church many years ago.Falling some twelve feet through pitch darkness into a mass of bones was too much for the individual to bear, and it is reputed that he lost his mind through the incident, remaining that way until the day he died. More latterly, the crypt has been reorganised such that the skulls are now displayed on shelves around the walls, and the thigh bones displayed in two large square piles in the centre. The 13th century crypt contains the remains of around 1500 individuals.It is thought some were first buried in the churchyard and then moved at a later date.A second burial within the crypt possibly took place around 1580 when the adjacent Jesus Hospital was built on what was perhaps an old burial ground.

Whatever the explanation and I very much doubt it is a sinister one, they do provide an extremely interesting experience.
