Manhattan Unlocked

Welcome to the blog

(I appreciate your patience as I upgrade and revise “The 30,000 Foot View” and “Decode the City: The Vortex and the Palimpsest”)

Beginning soon after the opening of the Erie Canal in 1825, but especially after Croton Water in 1842, three successive waves of built environment overran and over-wrote one another for the 4 miles between City Hall and Central Park, each was larger than the one before.

They were the modalities of life captured by the meme: live, work and play, but the order they moved uptown was: live, play and work.

Residential neighborhoods of homes, churches, clubs, hotels, and schools (live), were overrun by commercial cultures of shops and theaters (play), which in turn were overrun by commercial business in the form of manufacturing, industry and trade, and eventually white collar office towers (work).

A 3-dimensional cast iron and steel frame matrix rose from the 2-dimensional grid in increasing orders of density through which New Yorkers learned to live in apartment buildings, shop in department stores, and work in office towers.  

Manhattan Unlocked uses geography, transit and architecture together to explain the extraordinarily rich, inordinately complex history of New York City on the Island of Manhattan.
