This oak door belonging to Westminster Abbey, London; England. It is the oldest and only Anglo-Saxon door in Great Britain. The door has been standing for over 950 years, dating back to the reign of Edward the Confessor during the 1050s CE.
The door was made from a single oak tree from eastern England in medieval times. The oak piece has 5 main boards, connected by iron strips and wooden beams, and is approximately 2m high.

The carpenter who made this a thousand years ago probably complained that some part of the door didn't line up properly and that if they had more time, they could have done a better job.
There is a striking air gap at the top. That poor carpenter died knowing he did a shitty job (that we are now admiring)
The gap is not original, the planks were cut down and were most likely rounded at the top.
