The blast tunnel you have to walk through when entering the Diefenbunker, a great tourist site in Carp, Ontario, just west of Ottawa. It was the safe place that the government would be moved to in case of a nuclear war, named after the prime minister who had it built. Amazing place, especially the safe on the bottom floor that was meant to house the country's gold reserves. I didn't know that if gold gets hit by nuclear radiation it become worthless; so the economy would crash if the gold backing up the currency was destroyed. I'm surprised it's not a more well known tourist site. I'm also surprised that the curving lines all lined up when stitching the panorama together!
One of the many old alleyways in Siena, Italy. I never get tired of the buildings that connect by arches over the streets.
