I think anyone who was a tourist to Europe would be numb to big castles, etc. Yes, it would be very impressive to see them in their heyday rather than say a palace that was converted to a museum or tourist attraction, but as someone I watched give a video tour of a castle once said. The impressive thing to me it not the nobility who paid for the thing but the craftsmen and artists who made it. As someone who spent a lot of their youth working a garden center, I can really appreciate the years of work it takes to topiary those hedges for example.
