Founded by English Puritans in 1630 on the small Shawmut Peninsula, Boston became a flashpoint of the American Revolution — the Boston Tea Party and the opening battles of Lexington and Concord both trace back to meetings held in its streets. Landfill has since tripled the peninsula's original size, but the crooked colonial-era street plan survives downtown, unbothered by any later grid. Harvard and MIT sit just across the Charles River in Cambridge, anchoring one of the country's densest research and biotech clusters. In 1919 a ruptured molasses tank in the North End sent a wave of syrup through the streets, killing 21 people — a disaster still taught locally as the Great Molasses Flood.
