Chelsea is a city in Suffolk County, Massachusetts, United States, directly across the Mystic River from the city of Boston. As of 2013, Chelsea had an estimated population of 36,828.
The area of Chelsea was first called Winnisimmet (meaning "good spring nearby") by the Massachusett tribe, which once lived there. It was settled in 1624 by Samuel Maverick, whose palisaded trading post is considered the first permanent settlement by Boston Harbor. In 1635, Maverick sold all of Winnisimmet, except for his house and farm, to Richard Bellingham. The community remained part of Boston until it was set off and incorporated in 1739, when it was named after Chelsea, a neighborhood in London, England.In 1775, the Battle of Chelsea Creek was fought in the area, the second battle of the Revolution, at which American forces made one of their first captures of a British ship. Part of George Washington's army was stationed in Chelsea during the Siege of Boston.On February 22, 1841, part of Chelsea was annexed by Saugus, Massachusetts. On March 19, 1846, North Chelsea, which consists of present-day Revere and Winthrop was established as a separate town.Reincorporated as a city in 1857, Chelsea developed as an industrial center and by mid-century had become a powerhouse in wooden sailing ship construction. As the century wore on, steam power began to overtake the age of the sail and industry in the town began to shift toward manufacturing.Factories makingrubber and elastic goods, boots and shoes, stoves, and adhesives began to appear along the banks of Boston Harbor. It became home to the Chelsea Naval Hospital designed by Alexander Parris and home for soldiers.
