The Rotunda (New York City)

The Rotunda was a building that stood in City Hall Park in Lower Manhattan, New York City, from 1818 to 1870. Originally built as an art gallery to display panoramic paintings, the building was later used for a variety of other purposes, including as a courthouse, a naturalization office, a post office, and the offices of government agencies. The Rotunda was also the site of the founding meetings of the Century Association and American Society of Civil Engineers in 1847 and 1852, respectively.
