The old city of Edinburgh is a world heritage site by itself. The attractions include the Castle on the hill overlooking Princes Street (Oxford Street of the Scottish Capital), Palace of Holyroodhouse, The Royal Mile in between, Arthur's Seat (an extinct volcano) in Holyrood Park, St Giles Cathedral (small for a cathedral but containing the chapel of the Knights of the Ancient and Most Noble Order of the Thistle), The Firth of Forth, the University, St. Mary's catholic cathedral, numerous other old churches, the street where Sean Connery was born and was a milkman(he doesn't live there any more). I was there during the Festival in August, which is the largest Art event in the world. The city swells up in population as people from all over the world come to join in the festivities. You will never be bored because of the thrilling sounds of the bagpipes wafting over the hills. Don't miss the Military Tattoo if you can help it. They call it the "Greatest Show in the World", P.T. Barnum notwithstanding. The well-travelled Irish flautist James Galway once said that this city is his favourite city in the world.
