Boston was first discovered by an European when John Smith explored the New England coast in 1614. However it did not become an established settlement until the arrival of John Winthrop with 700 immigrants from England in 1630. Boston was an early centre of Puritanism and in 1865 established America's first public school. The Shawmut Peninsula, where the town was settled, was originally nearly completely surrounded by water.
The long shoreline provided ample space for wharves and shipyards. In 1800 the Boston Naval Shipyard was built and the waterfront was extended, with Black Bay being dammed (1818-21).

Fitzgerald's daughter, Rose Fitzgerald, was later to marry Kennedy's son, Joseph Patrick Kennedy: the parents of John Fitzgerald Kennedy, Robert Kennedy and Edward Kennedy.
