Drop City was an artists' community that formed in southern Colorado in 1965.
Abandoned by the early 1970s, it became known as the first rural "hippy commune".
As Drop City gained notoriety in the 1960s underground, people from around the world came to stay and work on the construction projects. Inspired by the architectural ideas of Buckminster Fuller and Steve Baer, residents constructed domes and zonohedra to house themselves, using geometric panels made from the metal of automobile roofs and other inexpensive materials. In 1967 the group, now consisting of 10 core people, won Buckminster Fuller's Dymaxion award for their constructions.
Soon the community grew in reputation and size, accelerated by media attention, including news reports on national television networks. The peak of Drop City's fame was the Joy Festival in June 1967, which attracted hundreds of hippies, some of whom stayed on. With the complex of eight domes and geometric buildings constructed, Curly and Jo, the only official owners of the property, signed it over to a non-profit corporation consisting of the entire core group (then about a dozen). The deed stipulated that the land was "forever free and open to all people". Tensions and personality conflicts were, however, already an inevitable problem within the group, and they soon became unbearable. By the end of 1968 some of the original occupants of the community had moved to Boulder, Colorado to start an artists' cooperative, "Criss-Cross", whose purpose, like Drop City's, was to function in a "synergetic" interaction between peers (no bosses) to create experimental artistic innovation. Among the innovative endeavors to evolve out of Drop-City are:
At Drop City, debris and building remnants from the original settlement remain at the site today, though it is not inhabited. In parallel with the demise of the Berkeley collective movement after the end of the Vietnam War, the energy ran out at Drop City. By 1977 it was abandoned, and the members of the non-profit who were still in touch decided to sell off the site to the cattle rancher next door. The last of the iconic domes was taken down only in the late 1990s, by a truck repair facility which now occupies a portion of the site.
