Circle Oaks, California

Circle Oaks is a small unincorporated community in the hills to the northeast of the world-famed wine region, Napa Valley. Created in 1964, this wildland interface has thrived since, growing into a small country community outside of a bustling valley. The land layout is purported to have been Frank Lloyd Wright's, the area consists of 1/4 acre lots that are perfect circles; the areas ("triangles") among the circles are considered to be "greenbelt" and cannot be built upon; these greenbelt areas are managed by the Circle Oaks Homes Association.
