IIRC they built a replica for Lescaux Caves to protect the real one from tourists and their lung humidity. May not be a viable solution in all cases, but maybe enough of them? Also too I want immersion in recreated scenes of plausible daily life. Also I wanna touch the things, that’s part of immersion.

While those places clearly need some relief from all the massive tourism, i think travelers should appoint themselves to add developing countries to their list (they could get a real boost from the tourist income 💵).
