Views and Vistas
This nearly barren island is visible from most points in the outer harbor. From the island there are views to surrounding outer harbor islands and inner harbor islands in the distance.
In the early 1600s, the island was named for Joseph Green, a well-known merchant, who owned the island during Colonial times.
