Carpenters' Hall is a two-story brick building in the Old City neighborhood of Philadelphia, Pennsylvania, that was a key meeting place in the early history of the United States.
Designed in the Georgian style by architect Robert Smith.
Completed in 1775 and set back from Chestnut Street, the meeting hall was built for and is still owned by the Carpenters' Company of the City and County of Philadelphia, the country's oldest extant craft guild.
The First Continental Congress met here. (copied from Wikipedia)
