In January, my wife and I went to see the Azure (Blue) Window on Gozo Island in Malta. It was a beautiful natural arch formed by years and years of erosion on the limestone. I used “was” because a couple of days ago the arch collapsed and totally disappeared.
When we were there I climbed partly up the rocks to get closer to the arch but did not walk across. Many people did. Later I heard that visitors had been prohibited from climbing on the arch. But I have also seen a video in which a man jumped off the arch into the sea below. As he jumped, some pretty big pieces of rocks came loose and felled - a clear demonstration of what people can do to damage the arch.
It has been said that erosion would cause the arch to collapse at some point anyway. But I would have felt quite bad if I had contributed to the collapse.
I don’t know whether to feel good, or bad, to have seen the arch which is no more.
