Explore the Civil War-era Fort Warren, enjoy a picnic lunch, or relax under a shady tree.

Dominated by Fort Warren, a National Historic Landmark, this 39-acre island is the center of transportation to the islands. The island is 53 acres at low tide.

Short History
At the time of Euro-American colonization, Georges Island was comprised of two drumlins, rising out of the bay like other nearby islands. The island sustained agricultural use for two hundred years until 1825 when the US Government acquired the island for coastal defense. Over the next twenty years the island was dramatically altered and one of the country’s finest forts was built. Dedicated in 1847, the fort’s defensive design was virtually obsolete upon completion. However the fort served as a training ground, patrol point, and Civil War prison that gained a favorable reputation for the humane treatment of its Confederate prisoners. After one hundred years of military use the fort was decommissioned in 1947 and acquired by the MDC for historic preservation and recreation in 1958.

Fort Warren is a National Historic Landmark, listed in the National Register of Historic Places.

Natural History Overview
Vegetation
The island has an intensive grounds maintenance program. Most of the island is mowed as turf. Steep slopes not mowed are colonized by tall grasses, wildflowers and sumac. Horsechestnut, elm and maple trees inside the fort are approximately 100 years old. Additional horsechestnut trees were planted by the MDC and are easily discernable. The island contains many apple trees, some planted and some self-sown. Pine and maple trees planted by the MDC in picnic areas offer wind and sun protection. Planters filled with annuals and perennials, installed by the MDC, are raised so not to disturb archeological resources.

Wildlife
Survey in progress.

Geology
Prior to 1833 the island consisted of two drumlins with elevations of 48 and 64 feet, similar to the topography of the east head of Peddocks Island. The fort was tucked in between the two drumlins and the island substantially regraded. The current highpoint of 50 feet exists at the top of the fort’s ramparts.

Water Features
Historically the island relied on cisterns for fresh water. The cistern is still visible on the parade ground near Bastion A. Fresh water is now supplied by a pipe from the mainland.

Views and Vistas
Located in the center of the harbor, the island offers excellent views to the surrounding islands and Boston Light, particularly from the ramparts and the siting towers: downtown Boston, Hull, Islands: The Brewsters, Deer, Gallops, Long, Lovells, Peddocks, and Rainsford Islands.
