Somerville Powder House
This old mill built by John Mallet on a site purchased in 1703-4, was deeded in 1747 to the 'Province of the Massachusetts Bay in New England' and for many years was used as a public powder house.
On Sept. 1st 1774 General Gage seized the 250 half-barrels of gunpowder stored within it and thereby provoked the great assembly of the following day on Cambridge Common, the first occasion on which our patriotic forefathers met in arms to oppose the tyranny of King George III; in 1775 it became the magazine of the American Army besieging Boston.
This tablet was placed by the Massachusetts Society of Sons of the Revolution Sept. 1st 1892.
