I must admit, I didn't really know this street was even here. The whole maze that makes up this neighborhood makes it very easy to overlook entire areas. When you're standing on Park Row, this block seems to disappear into the background; and why wouldn't it? You have so many prominent landmarks surrounding you, what use is it to notice Ann Street?
The block itself was a lot of fun to walk down. Full of incredibly narrow, yet tall buildings that cast uneven shadows on the ground. One third of the way down the street is Theater Alley, which Scouting NY had a great little write-up on recently.
Really, the key to this block is to keep your gaze skyward. Every rooftop and wall seems to have something unique to present. The street-level, by comparison, isn't all that much to look at.
