Discover Boston

A concise introduction to Boston, its geography, history and culture.

Introduction

Boston is the capital and most populous city of Massachusetts, and the cultural and financial centre of New England. It has a population of 675,647 as of the 2020 census — the third-most populous city in the northeastern United States after New York and Philadelphia — while the Greater Boston metropolitan area held about 5 million people in 2025.

It was founded on the Shawmut Peninsula in 1630 by English Puritan settlers, who named it after the market town of Boston in Lincolnshire. It was the largest town in the Thirteen Colonies until Philadelphia overtook it in the mid-eighteenth century, and it was where the American Revolution largely began: the Boston Massacre (1770), the Boston Tea Party (1773), the Battle of Bunker Hill (1775) and the Siege of Boston (1775–1776).

The city collects national firsts. Boston Common (1634) is the oldest public park in the United States; Boston Latin School (1635) the first public school; the Tremont Street subway (1897) the first subway system; and the Boston Public Library (1852) the first free library.

Today it is a global centre of higher education and research and one of the largest biotechnology hubs in the world, drawing more than 350,000 college students who contribute over $4.8 billion a year to the city's economy. It receives the highest absolute amount of annual National Institutes of Health funding of any American city.

Geography

Boston sits on Boston Harbor, an arm of Massachusetts Bay, on what was once a three-hilled peninsula barely attached to the mainland. Almost half the city's 89.63 square miles is water. Much of the land is not original: the nineteenth century filled in the tidal flats that became Back Bay, and the city annexed its neighbours.

History

Founded on the Shawmut Peninsula in 1630 by English Puritans who named it after Boston in Lincolnshire, and the largest town in the Thirteen Colonies until Philadelphia passed it. The Massacre of 1770, the Tea Party of 1773, Bunker Hill in 1775 and the Siege of 1775–76 all happened here. Afterwards the city outgrew its peninsula by filling in the sea, and collected a run of national firsts: the first public park, public school, free library and subway.

Culture

Called the "Athens of America" since the early 1800s for a literary culture that included Emerson, Thoreau, Hawthorne and Longfellow, and still shaped by its universities. It has its own accent, its own slang, a seafood-and-dairy regional cuisine, and a sporting life closer to a civic religion than a pastime.

How It Was Built and Evolved Over Time

Boston was built twice: once on the three-hilled Shawmut Peninsula it was founded on, and again on ground that did not exist until the nineteenth century made it. Filling the tidal flats produced Back Bay, and annexing neighbouring towns produced most of the rest of the modern city.

Climate Patterns

Warm, humid summers and cold, stormy winters, with about 13 days a year above 90°F and 25 below freezing. July averages 74°F (23°C), January 30°F (−1°C). Spring and autumn are cool and changeable. Boston gets over 2,600 hours of sunshine a year, which is a great deal for its latitude.

Frequently Asked Questions

How do I get in from the airport? The Silver Line. Service from Logan Airport is always free, and it runs to South Station. A free Massport shuttle also connects every terminal to the Blue Line at Airport station.

Do I need a transit pass? Probably not for a short visit. A subway ride is $2.40 and a bus $1.70; the 1-Day pass at $11.00 needs about five rides to pay for itself, and the historic core is walkable. For a week with daily travel, the $22.50 7-Day pass makes sense.

Can I walk the Freedom Trail in a day? The downtown half — Common to the North End — is a comfortable morning. Charlestown adds a long bridge walk to two monuments; take the ferry or the Orange Line back instead of retracing it.

When should I come? September to mid-October, or late May to June. Avoid Marathon weekend in April and graduation weekends in May unless that is why you are coming.

Is Boston expensive? Yes, mostly for hotels. Transit is cheap and the free layer — the Common, the Public Garden, the Esplanade, the Arboretum, the library, the harbourfront — is unusually good.

Is it safe? Yes, by visitor measures. The FCDO's national guidance is that violent and gun crime rarely affect tourists, with the usual advice not to walk quieter areas alone at night. Call 911 in an emergency.

Do I need health insurance? Yes, and it is the most important thing to arrange. Medical treatment is expensive and there are no special arrangements for British visitors; UK prescriptions are not valid.

Why are the downtown streets like that? They grew rather than being planned, on a peninsula. Back Bay and South Boston are grids because they were built later on land that had to be made first.

Is there free wi-fi? The city runs Wicked Free Wi-Fi on the SSID "WickedFreeWiFi", but coverage is neighbourhood-based rather than city-wide. Do not plan around it.
