Staid ones first. A mildly sinister military/industrial complex above left, and a handsome, vaguely religious octagon on the right (both Lower East Side). Note the vents; I guess the water would boil in summer without them.
Some drama. Above left, the Empire State Building and a bug-like helicopter line up with a modern water tower. On the right, a zigzag in Long Island City waits for a tank that will never come.
Reconfigured. Above left, a Greenpoint tank turned into a cellphone tower (do the microwaves heat the water?). On the right (off Lexington above 23rd), it looks like a newer, bigger tank is perched on the old one's tower.
Finally, two of my favorites. On the left, a tank perched dramatically next to the New Museum on Bowery. And on the right, a small temple seen on a hazy day (on E. 9th just east of Broadway).
