History of Boston is described below.
Explanation:
- When workers cut down Copp's hill the only thing they left untouched was the old three-acre burying ground. The city built a retaining wall around the graveyard to prevent it from eroding. In 1814, the Boston and Roxbury Mill Corporation built the Boston & Roxbury Mill Dam across the back bay
- Originally called Tremontaine for the three hills in the area, the Puritans later changed the settlement's name to Boston, after the town in Lincolnshire, England, from which many Puritans originated.
- South Boston, which was front and center in the battle, is no longer that close-knit old school “tough-as-nail” Irish Catholic enclave. “Southie,” as it is still fondly referred to, houses the world today flaunting some of the best restaurants and expensive housing in the city
- Boston was founded in 1630 by English Puritans fleeing religious persecution. On 29 March 1630 a fleet of 11 ships carrying 700 people sailed from England to Massachusetts. They were led by John Winthrop (1588-1649). At first the people settled at Charlestown, which had been founded the year before.
- Much of Boston's coastline is man-made land. The original shoreline, from 1630, is visible in dark green on this map. Land made between 1630 and 1995 is light green.Boston is a safe city, but as with any major city, you should take the usual safety precautions. Stay in well-populated areas, travel with others, especially at night, and keep track of your belongings. The tourist areas in Boston are generally safe, but some areas deserve mention.
