Watertown.

Watertown packs an impressive amount of life into about four square miles on the north bank of the Charles River. Just six miles from downtown Boston, with Cambridge next door, it has grown from a quiet streetcar suburb into one of Greater Boston's liveliest small cities — home to a fast-expanding life-science corridor along Arsenal Street, a riverfront stitched together with parkland and bike paths, and Arsenal Yards, where a former Army arsenal complex now holds shops, restaurants, a cinema, and new apartments.

There is no subway station in Watertown itself, but the bus network fills the gap better than most newcomers expect. The 71 runs frequently between Watertown Square and the Red Line at Harvard, the 57 links Watertown Yard with the Green Line at Kenmore, the 70 travels Arsenal Street to Central Square in Cambridge, and the 504 express carries commuters straight into downtown Boston. Drivers pick up the Mass Pike at the Newton Corner interchange, and the Charles River Greenway makes a bike commute to Cambridge or Boston genuinely practical for much of the year.

The housing mix leans classic streetcar suburb: two-families and triple-deckers on tight-knit side streets, Victorians and Colonials on the rise toward Belmont, postwar capes and ranches in the west end, and a growing supply of newer condos and apartments near the river and Arsenal Street. Prices generally land a notch below Cambridge and Newton next door, which keeps Watertown high on the list for buyers who want walkable squares without paying those neighbors' premiums — though competition here is very real. Daily life revolves around Watertown Square and Coolidge Square, where the Armenian bakeries and markets along Mount Auburn Street reflect one of the country's most storied Armenian-American communities.

Watertown Public Schools serves the city with three neighborhood elementary schools — Cunniff, Hosmer, and Lowell — plus the Early Steps integrated preschool. Watertown Middle School covers the middle grades, and Watertown High School serves grades 9–12. The city has invested heavily in its school buildings in recent years: Cunniff and Hosmer were rebuilt from the ground up, and a brand-new, net-zero Watertown High School building is slated to open for the fall of 2026.

Watertown is also home to the Perkins School for the Blind, whose landmark campus has overlooked the Charles since 1912 and serves students from around the world.

• History

Watertown was settled in 1630 by Puritan colonists led by Sir Richard Saltonstall and Rev. George Phillips, making it one of the very first communities of the Massachusetts Bay Colony, and its falls on the Charles powered some of New England's earliest mills. During the opening years of the Revolution the Provincial Congress met here, briefly making Watertown the seat of Massachusetts government. The Watertown Arsenal manufactured munitions for the U.S. Army from 1816 into the 1960s, and its grounds have since been reborn as offices, labs, and the Arsenal Yards district. In the early twentieth century, immigrants drawn by factories such as Hood Rubber built the Armenian-American community that remains central to Watertown's identity today.

Watertown occupies the north bank of the Charles River about six miles west of downtown Boston, in eastern Middlesex County. It borders Cambridge to the east near Mount Auburn, Belmont to the north, and Waltham to the west, while across the river lies Newton, with Boston's Brighton neighborhood meeting the city's southeastern corner. River crossings at Watertown Square, North Beacon Street, and Arsenal Street keep both sides of the Charles within easy reach.
