400 Year Old Cat Door in Exeter Cathedral, Oldest Known.
It's still very much in use for the occasional rodent. The clock in this room was originally lubricated with lard which attracted mice and rats. It's thought the nursery rhyme Hickory, Dickory, Dock was written about this Astronomical clock that is still in operation.
Installed in 1598 by Bishop William Cotton who was appointed by Queen Elizabeth I, "Paid ye carpenters 8 pence for cutting ye hole in ye north transept door for ye Bishop’s cat."
Interesting fact some may not know: in the phrase you quoted, the "ye" words are pronounced as "the", not "ye". The y is a substitute for a letter not used anymore.
@SinlessOnslaught I think it started to die out in the 18C, along with the elongated version of "s" that resembles an "f"; but which became the integral symbol in maths.
Hickory Dickory Dock, three mice ran up a clock. The clock struck one, and the other two escaped with minor injuries. Footage and a discussion panel at 11pm tonight.
