An intentional community is a community of people with a shared goal or shared interests living together. Environmental responsibility is often both a goal and result of the living arrangements. Quakers have been involved in the organization of a number of intentional communities around the world and materials related to a few of these communities can be found in the Friends Historical Library.
Bryn Gweled Homesteads was founded in Bucks County in 1940 and still exists. Information about Bryn Gweled can be found in the Howard Haines Turner Papers.
Tanguy was founded in the mid-1940s in Chester County. The Mary Ellicott Arnold Papers have further details on this community.
Although slightly different from the examples listed above, Monteverde is located in Costa Rica. A group of American pacifists, mostly Quakers, moved to Monteverde in 1951, where they have lived since. Monteverde Quakers and the local community worked with Quaker Earthcare Witness in the 1990s to create the Finca la Bella community farming project in the San Luis Valley. The result is both a forest preserve and traditional farm. The collections about Monteverde in the Friends Historical Library include records of the Monteverde Monthly Meeting and Monteverde Friends School/Escuela de los Amigos in Monteverde.
