There have been a few collapses already in the past few weeks due to the stormy weather but they might not have been seen by people unless they were familiar with the structure. Obviously this one is more noticeable and it is a great shame.
It is an unmaintained ruin so this was always likely to happen and the extremely high winds have taken their toll. It is very, very sad.
The more collapses that happen, the weaker the structure becomes and so more collapses become likely. Our engineers can only stand and observe.
