It is absolutely magnificent place to be at! Atleast to witness the old age and get to see what we have missed over the centuries. These sort of places does kind of reminds me of GOT : )
Sometimes I just wonder how amazing the architect were in the past. With limited resources they have built places which has lasted for centuries and not to forget about the architecture which are fascinating as well. If I ever get the chance I will definitely explore one of these places just to see how it actually feels lol.
you are right, they used to build things that are still there today!!!
