The leaning tower
Wide Wednesday: Leaning
This is the leaning tower from Temple Church in Bristol. Dan Brown fans might want to know that it is built on a former Knights Templar site, so could perhaps harbour some clue as to the location of the Grail, after all Glastonbury is not that far away.
Temple Church is now just a shell, all that is left of the original 12th-century church which was badly damaged by the bombing of Bristol during the Second World War. As you can see, the church tower leans rather like the tower at Pisa. The historical records suggest that the tower started leaning back in the 15th century so it definitely hits the challenge requirement dead centre.
