Colonel Richard Ayres was granted the lease of Green Island in 1673.

[1] Green Island is located off the southeastern peninsula of Antigua, at the southern entrance to Nonsuch Bay.

The island itself measures about two kilometers from west to east; its width varies by two south-facing peninsulas in the range of a few hundred meters (maximum 650 m),[2] forming several sheltered bays.

[3] A sea-side peninsula ends in the Man of War Point, as the eastern tip of Antigua (as a region, east point of the main island the Neck of Land), from which the Atlantic Ocean[4] extends over nearly 4,000 kilometers to the approximately latitude Cape Verde.

The island forms part of Antigua’s Offshore Islands Important Bird Area (IBA), designated as such by BirdLife International because it supports significant populations of various bird species, including West Indian whistling-ducks, brown pelicans, laughing gulls, and least and royal terns.
