East Boston (Eastie) is a neighborhood of Boston, Massachusetts with approximately 40,000 residents. The neighborhood was created by connecting several islands using landfill. It was annexed by Boston in 1836. It is separated from the city proper by Boston Harbor and bordered by Winthrop, Revere, and the Chelsea Creek. Directly west of East Boston, across Boston Harbor, is the North End and Boston's Financial District. East Boston has long provided a foothold for the latest immigrants with Irish, Russian Jews and then Italians alternating as the predominant group. From the 1990s into the early millennium, Latin American immigrants settled in East Boston. In recent years, East Boston has become home to a wave of young professionals seeking residence in Boston in newly renovated condominiums along Jeffries Point, Maverick Square, and the Eagle Hill waterfront. Jeffries Point specifically has become one of the most desirable neighborhoods, due to its location to the harbor, marinas, and Piers Park. The Kennedy family resided in East Boston. The neighborhood is easily accessible to downtown Boston via the MBTA Blue Line. Originally, six islands made up the East Boston neighborhood. To connect to the mainland, routes, highways, and bridges had to be built. Some popular structures built to bridge that gap between the islands and the mainland include the Tobin Bridge, the Sumner Tunnel and the Callahan Tunnel. The Logan Airport is located in East Boston connecting to international locations.
