Dorchester is a historic neighborhood comprising over 6 square miles (16 km2) in Boston, Massachusetts, United States. The town was founded by Puritans who emigrated in 1630 from Dorchester, Dorset, England.
May 30, 1630, Captain Squib of the ship Mary and John entered Boston Harbor and on June 17, 1630, landed a boat with eight men on the Dorchester shore, at what was then a narrow peninsula known as Mattapan or Mattaponnock, and today is known asColumbia Point (more popularly since 1984 as Harbor Point). Those aboard the ship who founded the town included William Phelps, Roger Ludlowe, John Mason, Samuel Maverick, Nicholas Upsall, Capt. Roger Fyler, Henry Wolcott and other men who would become prominent in the founding of a new nation. The original settlement founded in 1630 was at what is now the intersection of Columbia Road and Massachusetts Avenue. (Even though Dorchester was annexed over 100 years ago into the city of Boston, this founding is still celebrated every year on Dorchester Day, which includes festivities and a parade down Dorchester Avenue).
