About Downtown
Watertown
Downtown Watertown, located between Watertown Square and the Charles River, is a commercial and civic Watertown neighborhood with a walkable main street and a river-edge backdrop. The neighborhood’s character concentrates around Watertown Square at Main Street and Mount Auburn Street, where cafés, longtime eateries, small shops, and bus stops keep the sidewalks in motion. Community pillars include the Majestic 7 movie theater, the Watertown Free Public Library, and the Armenian Museum of America. Brick storefronts and compact mixed-use blocks give the streets a classic New England center feel. Pocket greens and the river paths add breathing room between errands and evenings out.
