During my early years at the museum, there was a mystery we never cleared up.
The doors to the lower church - incorrectly referred to as the Crypt - have an inner 1/4 inch thick glass interior security set of doors.
One day, two of the of the archaeological diggers came the through the doors - the wrong way -with a ladder. From the outside, the door will open only about 1/2 an inch, then the copper hinges will stop the movement. These people came through with such force, not only did they buckle the hinges, they smashed the plate glass doors.
Despite the lower church floor being covered in shards of glass for several feet, neither of the men had a slight scratch.
The Church does have a crypt but not here, the church also has a Charnel House dating back to the plague. I can say in honesty, it's not a nice place to go inside.
The Museum curator at the time was the same one I mentioned in my book Sexual Explosions https://www.draft2digital.com/book/32234. The connection being I reported some stolen items from the Roman collection in Bristol Museum to him.
That is another mystery - or is it?
It certainly involved a police cover up.
