Originally built as a windmill, the old Powder House became property of the colonial government by 1748, and held the largest supply of gunpowder in the colony. After the Boston Tea Party, General Gage - of the British military - tried to control further rebellion by seizing military items from around the colonies. On the early morning of September 1, 1774, 260 British soldiers rowed to Somerville, marched to the Powderhouse and removed barrels of gunpowder. This incident sparked the "Powder Alarm" and was considered the rehearsal for the Revolution that started nine months later.
