Age unknown

I noticed this doorhandle in one of the outbuildings in the Prague castle complex; unfortunately, I didn't make a note of which one. One of the fascinating things about Europe to a North American, of course, is the fact that so many buildings and towns are vastly older than anything in the New World. On the other hand, lots of cities with famous monuments or buildings (like Prague) have restored or even rebuilt buildings that were damaged or destroyed by accident, war, etc. So it's always tricky to tell whether something that looks really old really is very old.
