I subscribe to “American Heritage of Invention and Technology” magazine. I just received a new issue, and saw an article in it about some sights online with photographs of old ruins and abandoned industrial installations. Listed in the article are Modern Ruins Photographic Essays and Undercity.org. I have no idea why these are so interesting, but they seem compelling enough for me to post about them. There are so many good photos, that picking any to show as samples is tough. Note that both sites make the photos available for sale as well as being available for viewing online.
This second photo is Manhattan Seen Through the Windows of the Renwick Smallpox Hospital Ruin.
I found it a bit depressing to think about.
