Chelsea

Chelsea is an industrial city in Suffolk County, Massachusetts, located on the banks of the Mystic River, directly across from Boston. Covering about 2.5 square miles (6.5 square kilometers) in total area, it ranks among the most compact cities in the state, with a dense mix of residential and commercial zones.

Samuel Maverick established a trading post in 1624 at the site then called Winnisimmet by Native Americans. The settlement was later renamed after the London district of Chelsea and grew into an industrial center during the 19th century.

The name comes from the Chelsea district in London, reflecting a link to English heritage. Today the city is home to a large Hispanic and Latino community, visible through storefronts, restaurants, and bilingual signage along the streets.

The city connects to Boston through several bus routes and the Silver Line, making it easy to reach the downtown area. Visitors planning to explore on foot should wear comfortable shoes, as many streets feature inclines.

The Battle of Chelsea Creek in 1775 was one of the first naval engagements of the American Revolutionary War, fought in the waters off the city. This clash is often overlooked, though it played a role in the early conflict across Massachusetts.
