It’s just gym equipment that’s designed to be durable outdoors. Kind of like jungle gyms but for adults. I’ve seen it in Cape Town, Milan, London, Auckland and always they are busy.
I have seen that, yes. Those jungle gyms are generally on a flat piece of grass that normally would be open and also relatively small. I thought it was more of a proper park - think full of bushes, trees, ponds, trails, birds etc. I haven't seen jungle gyms in places like that, which of course would be detrimental to the nature.
