Boston is home to the nation's first public park (The Boston Commons 1640), the first public library (1653) and the first subway (1897).
The Custom House Tower is a 29-story skyscraper that is a masterful blending of two very discrete styles. The original building was built in 1847 in the Greek Revival style in a crucifix shape that featured 36 Doric granite columns (only 1/2 of which actually supported the structure) and which weighed some 42 tons each. Each of these columns was carved from a single piece of granite. Atop this original structure was also a magnificent dome reminiscent of the Pantheon.
