The exact source of the design for the city center remains a mystery, but there are at least two very good possibilities. First is that it was patterned after the hexagonal barn at the Page ranch, which in turn may have been built along lines that were in fashion at the time of its construction. Another possibility is that it was fashioned after the radiating star plan which is prevalent in the layout of many European cities, as well as Washington, D.C. and Detroit, Michigan. Whatever the reason for its design, it was deemed unique enough to gain State Historical Landmark status in 1973.(Submitted on October 2, 2008, by Syd Whittle of Mesa, Arizona.)
Additional commentary.
1. Landmark has multiple errors
The 1975 petition for this landmark was based on erroneous information that has been repeated endlessly ever since. Local historians are working to have a new one made.
There is no evidence of another hexagonal town plan like this in the United States. It is unique in the Americas, according to experts in hexagonal planning. It was designed in 1892 by Newton Smyth for Wilfred Page, son of Thomas Page who had been dead for 20 years. Wilfred had six brothers making him one of seven. The streets around the plaza are named for them. There is a street further north named for Wilfred.
Also there never was a local chief named Cotati. This area is Coast Miwok territory, not Pomo, and they do not have chiefs. The name comes from a traditional Coast Miwok village. Also, Chieftan is misspelled.
This plaque is a mess that needs fixing. For more information, contact the Cotati Historical Society and Museum, www.cotatimuseum.org
