It is enclosed by an iron and granite fence dating from 1858.","why_significant":"It is the only surviving Revolutionary fortification in Cambridge, one of a series of half-moon batteries built in 1775 by order of General Washington to protect the town from attack by river. It is also considered an early example of historic preservation by private and public groups, since the Dana family gave the land to the city in 1857 for use as a park.","narrative":"Fort Washington is a small public park at 95 Waverly Street in Cambridge, Massachusetts, centered on a semicircular earthen battery from 1775. The battery was one of several half-moon fortifications ordered by General Washington to guard Cambridge against attack from the river, and it is the only Revolutionary fortification still surviving in the city. It measures about 120 feet across and has three openings for artillery facing southeast, south and southwest. In 1857 the Dana family deeded the land to the city, which worked with the Commonwealth to restore the battery, landscape the grounds and mount three 18-pound cannon obtained from Fort Warren in Boston Harbor. An elaborate granite and iron fence designed by John R. Hall followed in 1858, with cannon-shaped posts and spear and halberd pickets. Bronze tablets were added in 1928. The site is valued both for its Revolutionary War associations and as an early preservation effort.","period_of_significance":null,"architect_builder":"John R.
