Edinburgh Castle
In the eyes of many, this is the ultimate symbol of Scottish nationhood.
Certainly, it was the front-line bastion of the country's defence often enough.
Here the royal regalia of the Kings of Scots are preserved, while its walls overlook the annual spectacle of the Edinburgh Military Tattoo and welcome more visitors than any other castle in Scotland.
