That's a very cool blog, and some amazing places I'd love to see myself someday. I've always had a fascination for abandoned, closed, ruined, or ghost-towned places and structures...and they are great subjects for photography.
I've got a few that might fit the category, from my travels...
California Lighthouse, Aruba:
Abandoned house, Uvita Island, Costa Rica:
La Pulperie, abandoned pulp mill in Chicoutimi, Quebec:
Abandoned fishery processing plant, Sydney, Cape Breton:
Abandoned Fort George, overlooking the harbor at St. George's, Grenada:
