New York State Capitol

The New York Capitol Building, inspired by a French chateau and Romanesque/French Renaissance styles, took 32 years to build (1867-1899) with contributions from five architects. The Great Western Staircase, designed by Henry Hobson Richardson and completed by Isaac G. Perry, had a skylight and lighting praised for perfection. A fire in 1911 caused significant damage, leading to modifications during WWII and the 1960s. A restoration project in 2000, led by Quarra Stone, revived the Capitol’s grandeur, with meticulous replication of the skylight and laylight while preserving historical character.
