Salisbury Cathedral

Salisbury Cathedral has a slight problem. The crossing tower (the tallest in the UK) was too heavy for the structure underneath it. There were three attempts to counteract this problem with buttresses, arches, and finally iron ties. So there is a slight tilt visible from the outside and the columns underneath are impressively bent. I did not know anything about this before visiting, my first inkling of the issues were the interior bracing arches above the bending columns...
