To answer @Amerzarak's question, the abbey is in a rural setting without an immediate surrounding community of researchers or urban resources. So, yes, no air-conditioning. The floors are polished; the ticket-takers are friendly, and the guides have a handful of stories that they tell well. For aesthetics, it would be nice if they can preserve everything. But in terms of scholarly impact, this wouldn't be on my list of the world's 1,000 historic collections most worth preserving in their entirety.
