Canalside Cover-Up

I feel like I’m about to be sealed into the cliff forever, like some kind of frozen pod. The handrails look like they’ve been supercharged by some kind of electricity and it’s going to zap me straight in. I could cook, be transported somewhere, or be frozen instantly. It must be hydropowered by the canal below. The hole in the left of the wall could be the release mechanism. You’d probably need a key. I’m not sure if that’s my revenge pose or if I’m preparing to knock on someone’s door. Perhaps there’s a glass door in place that’s sealed me into the cliff already. Will I be put on show as a warning to trespassers, or will the vines above be lowered down to hide me? I wonder what my crime was. Perhaps my backpack contains a supply of clothes for a few days to allow me to blend into this new society.
