In the 1960s, Marincello was a proposed community for nearly 30,000 people which would have been situated in the Marin Headlands, military lands that were soon to be vacated by the US Army. This 10 foot by 10 foot model shows apartment towers, new waterways, schools, churches, and shopping areas that would have been included in the new city. Through the work of a local organization, Headlands, Inc., enough opposition was created to stop development, which had already begun grading roadways and small construction projects. The individuals in this group, and many other nearby grass-roots organizations, believed in preserving land and history near an urban environment for the enjoyment of future generations.
