One of the most unique green spaces in this vast metropolis, it straddles a building and doesn’t offer much in the way of respite or convenience, but beats development. ” This small park is a memorial to a not-quite-gone and not-quite-forgotten water feature of Lower Manhattan. When Dutch colonists settled in Manhattan in the 1620s, they learned from local Native Americans about a small brook that was full of trout. It originated near what is now Gramercy Square, burbled its way through(mostly beneath) Greenwich Village, and emptied into the Hudson at what is now West Houston Street.”
