Philadelphia - Old City Hall

Built as the City Hall of Philadelphia, the building was used by the U. S. Supreme Court from the time the building was completed in 1791 until 1800 when the Federal Government was moved to Washington D. C. The municipal government and courts occupied the building during the nineteenth century.
Independence Hall is flanked by Congress Hall, in which the first Congress of the United States met from 1790 to 1800 and George Washington and John Adams were elected President, and Old City Hall, which was never in fact the town hall but was the seat of the Supreme Court from 1791 to 1800.
