World Fellowship Center. Conway, New Hampshire

Though she is most known for her Prairie School designs, Marion Mahony Griffin devoted herself to writing and progressive causes in the late 1930s and ’40s. Working with American pacifist and feminist Lola Maverick Lloyd, Mahony Griffin planned a large, unrealized retreat center for the peace organization World Fellowship of Faiths. Intended to celebrate the power of individuals to pursue peace after the trauma of the war, Griffin’s geometric design blends a colony of cottages and recreational facilities into the topography of the landscape.
