This street, just south of Stuyvesant Square, has a lot going for it in terms of architectural and natural beauty. It lacks any commercial presence, save for the two bustling avenues which flank it (and 14th St to the south), so don't come here looking for anything other than a brief stroll through the park (or worse, a visit to the hospital).
Stuyvesant Square has the amusing characteristic of being split down the center by 2nd Avenue- a feature shared only by a handful of other Manhattan parks (Trinity Park, and Sara D Roosevelt Park come to mind)- obviously for the purposes of this blog and post, I can only speak to the eastern side.
When I approached the park today, I initially thought it was closed as no one seemed to be within it's gates. I was wrong, as all the entrances were open, I assume it was just too damn cold for most folks. The park itself features your standard array of wrought iron fencing and plastic signage. Overall it's very pleasant and lends an otherwise dead street some "visitability".
The buildings on the south side have some great pre-war detailing, which I always appreciate. About 1/3 of the way down the street (walking east) is Nathan D Perlman Place, which creates the eastern most boarder of the park (Beth Israel has buildings across the way). There's a bus shelter right after that, which I can't for the life of me find on any map. I assume it's for some private hospital bus. As one approaches 1st avenue there's Stuyvesant High School, which despite it's years of paint, has some really cool iron work and building design elements. At the very end of the block there's a Chase bank and Ruby's Japanese & Thai Cuisine (though both of their entrances are basically on 1st ave.)
