About Central Maverick Square-Paris

Street

Central Maverick Square-Paris Street, located between Maverick Square and the Paris Street corridor, is a waterfront and transit-linked Boston neighborhood with brick rowhouses and harbor-view streets. The neighborhood’s character concentrates around Maverick Square by the MBTA station, where corner bodegas, longtime eateries, and ferry-bound foot traffic set a brisk, everyday rhythm. The ICA Watershed anchors contemporary art on the working waterfront, while the East Boston Shipyard and Piers Park frame the area’s maritime past and open-air promenades. Triple-deckers and compact blocks give way to newer mid-rises near the waterline. Side streets climb toward Eagle Hill with pocket parks and small storefronts. Ferries and the Blue Line shape a walk-forward, city-facing routine.
