Unsuspecting landmarks

One Chase Manhattan Plaza and the Consolidated Edison Building are now landmarks according to the New York City Landmarks Preservation Commission.

Constructed mainly of aluminum and glass, the Plaza was designed by Skidmore, Owings & Merrill and was the sixth-tallest building in the world at the time of its completion in 1961.

The Con-Ed building began construction in 1911 and was designed by Henry J. Hardenbergh.
