I didn’t know what all the tanks on the rooftops were when I took the photo. As usual, Wikipedia knew the answer: they’re water tanks that were mandated in the 1800s in order to maintain water pressure in buildings over 6 stories. Presumably they’re still there because they work, but they’re a little precarious looking. Makes me wonder how New Yorkers can possibly claim their city water tastes good – maybe it’s like fine wine aged in oak barrels?
