About Watertown West
End
Watertown West End, located between the Charles River and Belmont, is a residential and commercial Watertown neighborhood with riverfront paths and a low-rise streetscape. The neighborhood’s character concentrates around Arsenal St at School St, where sidewalk storefronts, coffee counters, and small studios meet steady foot traffic. Community pillars include the Mosesian Center for the Arts, the Majestic 7 movie theater, and the Watertown Free Public Library. Brick mill buildings and mid-century apartment blocks mix with compact side streets of classic New England houses. The Charles River Greenway frames daily routines with long views and bike flow. Arsenal Yards adds a modern plaza feel without overpowering the older fabric.
