Perched atop Spring Hill between Lowell and Belmont Streets, this simple park offers benches and old shade trees as well as a grassy knoll for picnicking or sunbathing. At just about 3/4 of an acre, it's petit but nicely designed with four spokes leading to a central circle of benches. Somerville Hospital is nearby and the park offers its visitors an outdoor respite. On-street parking is free, but by permit.
