The original World Trade Centre, New York City. The North Tower (left) is 1 WTC. The South Tower (right) is 2 WTC. The red granite-clad building left of the Twin Towers is the original 7 World Trade Centre.
The Chrysler Building in New York City, a pinnacle of art deco style. I personally much prefer the style of this building to the Empire State Building because this is a little more grand to me but not inappropriately so.
