Vandalism is a regular problem in Crystal Palace Park. The statues are not spared. Trespassing normally comes in the form of bravado displays.
Eric Boardman’s YouTube video, with him paddling in the tidal lake, shows a typical example. He laughs as he crashes into a Plesiosaurus statue. That statue shows cracks on its side. Related? This is no accidental passing by from a causal boater. The water here is separated from the boating lake by dams and other barriers. Someone must have physically lifted that boat into this pool of water.
This young man was working hard to impress a girl. Those statues were not designed to take this weight. It would be impossible to replace the Iguanodon if it collapsed.
These young men were doing the same, whilst their friend hides behind the Hylaeosaurus.
Here, a couple seeks an isolated spot to share a spliff (judged from the smell).
