New York, a city which is defined by its skyline, existed as a metropolis well before skyscrapers and has gone through several distinct architectural phases.I’ve picked this collection to demonstrate these, from the earliest known photograph of New York in the 1840s which shows the Upper West side as rural, to the Brooklyn Bridge dominated skyline of the mid nineteenth century.A postcard from 1904 is labeled ‘New York Skyscrapers’ but shows very few of what we would call skyscrapers today, consisting of the early steel framed buildings epitomized by the flatiron.Between the 1920’s and 1930’s the machine age skyscraper city of masonry-clad, art deco splendor grows at breakneck speed and remains similar in texture until the emergence of curtain wall, glass and steel buildings in the 1950s, after the completion of the Seagram in 1958.The 1973 opening of the iconic World Trade Center coincides the building of other inferior block like buildings along the periphery of lower Manhattan, notably at Water St., which destroy the hill like collection of spires.
