This former vacant lot on a prominent corner in Boston’s Beacon Hill Historic District has been transformed to a private pocket garden. The site is identified as a highly sensitive groundwater protection district, formerly at the edge of a sea wall which retained the Charles River. As the previous grade of the site was several feet below the sidewalk, the elevation was raised to bring the site entry level with the adjacent street. Intricate paving patterns and ironwork reflect the historic setting while flowering trees and perennials create a layered garden. A small greenhouse provides space for unique plants and shade for entertaining.
