St Leonard's Ossuary, Kent
You don't get much for £1 these days but a visit to the ghoulish St Leonard's Church Ossuary in Hythe, Kent is a pound well spent.
With remains dating back to the 13th century, the ossuary is Britain's largest containing over 1,000 skulls and the bones of around 4,000 people.
After much research and a plethora of theories, it is thought that the remains are those of Hythe residents that have been moved over the centuries from St Leonard's and other local churches.
