Old Massachusetts State House, 206 Washington Street (corner of State Street), Boston, Suffolk County, MA

Significance: The Old Massachusetts State House is the oldest extant public building of Georgian design in the United States. Built in 1712-13 to replace an earlier structure of wood completed in 1658 and destroyed by fire in 1711, the Old Massachusetts State House, or Second Town House, served a variety of purposes for the Province, for Suffolk County and for the town of Boston. This building became the State House of the new Commonwealth of Massachusetts in 1776, and remained so until 1798 when the legislature moved to the State House on Beacon Hill.
