Old State House is dedicated.

Architect: Robert Twelves (?). Originally the Town House (second), it is designed in the Georgian style and located at today’s 206 Washington Street. The oldest public building in Boston (and second oldest in the U.S. after the governor’s house in Santa Fe), its cornerstone was laid on May 5, 1712. The building includes a first-floor merchant’s hall and houses the General Court (Governor’s Council and Massachusetts Assembly) on the second floor. A visitors’ gallery is added in 1767.* A fire destroys the building’s interior on December 9, 1747, and it is rebuilt in 1748. It serves as the Massachusetts State House from October 25, 1780 until 1798.* The building is altered by Isaiah Rogers in 1830, serves as Boston City Hall from September 17, 1830 to March 18, 1841, is used for commercial purposes, and then preserved for public use in 1881.*
