The Second Continental Congress met primarily at the Pennsylvania State House in Philadelphia, which is now known as Independence Hall. The Congress convened there beginning on May 10, 1775, shortly after the war with Britain had started

. During the Revolutionary War, as the British threatened Philadelphia, the Congress temporarily relocated several times:

• Winter of 1776-1777: Henry Fite’s Tavern in Baltimore
• September 27, 1777: Lancaster Courthouse (one day)
• September 1777 to June 1778: York County Court House in York, Pennsylvania

After the British evacuated Philadelphia in June 1778, the Congress returned to Independence Hall

. Thus, the main and most significant meeting place of the Second Continental Congress was Independence Hall in Philadelphia.
