Nitt Witt Ridge, Folk art residence in Cambria, United States.

Nitt Witt Ridge is a residence built on a hillside in Cambria, California, United States, constructed from recycled materials including beer cans, abalone shells, and car parts. Multiple terraces and walkways connect the different levels of this unconventional structure that climbs the slope above the town.

Arthur Harold Beal acquired the land in 1928 and began building this unconventional structure, expanding it over five decades using simple tools like picks and shovels. Construction continued until shortly before his death, with Beal consistently incorporating found objects and discarded items from the local area.

Beal called himself Der Tinkerpaw or Captain Nitt Witt, and the name Nitt Witt Ridge puns on the ridge where he built. The site is California Historical Landmark No. 939, a plaque placed in June 1986 by the State Department of Parks and Recreation with Saving and Preserving Arts and Cultural Environments and the Art Beal Foundation. It is listed as a twentieth-century folk-art environment.

The property sits on Hillcrest Drive above the town center and remains visible from the street, though access may be limited. Visitors should respect private ownership and check current access policies before planning a visit.

Beal's ashes were scattered around his favorite redwood tree on the property after his death in 1992 at age 96. The house is California Historical Landmark No. 939, a plaque placed in 1986.
