My partner shot the inside of the spire, but I have a few quick shots.
On one of the sides I did - there were the traces of what we could only assume to be some type of explosion (probably a stray explosive from WW2 ..?).
There are also the eagles that were halfway up the spire.
Curiously enough, there were six, each one had a number stamped on its head - if you traced the numbers, it made a star composed of 2 equilateral triangles.
It seems the North Tower has since caught fire as well - so the bells will have gone, and all of the stored relics too - so some photos of those.
No, they're in the North Tower.
The bells are suspended in a wooden structure that is free-standing, and free moving inside the stone structure.
This allows free movement when the bells are ringing, without stressing the stones.
It was a priority to extinguish the north tower fire to prevent the bell structure from collapsing - the falling bells would have destroyed the stone structures on the way down, presumably triggering the collapse of both towers..
