Fort Williams Park in Cape Elizabeth, Maine, is a 90-acre public ocean front park on Casco Bay.  Home to Portland Head Light, the Park has matchless scenic views, diverse ecosystems, bountiful recreational sites, and a long maritime and military history.

Fort Williams has approximately 800,000 visitors annually and is enjoyed by visitors from near and far.  It is open and free to the public, 365 days of the year.

The Fort Williams Foundation was chartered in 2001 by the Cape Elizabeth Town Council and the Fort Williams Advisory Commission to preserve and enhance the natural and historic resources of Fort Williams Park for future generations by providing funding support and stewardship for selected projects within the Park.

The Arboretum is the Foundation's first major environmental preservation initiative and is creating sustainable landscapes which will inspire, educate, and be a continual reminder of the importance of the natural world.
