Town History

                                                               Town History

The Moraga Historical Society was established in 1965 to gather and preserve knowledge about the history of the Rancho Laguna de los Palos Colorados, which is now the Town of Moraga, plus portions of the cities of Orinda and Lafayette. The Rancho was a 13,316 acre land-grant to Joaquin Moraga and his cousin, Juan Bernal, by the Mexican government in 1841 – in return for service in the armies of  Mexico. Between 1912 and 1923, the Moraga Company, headed by James Irvine, owned most of the Moraga Valley, and in 1914, there were 38 pear orchards, plus a number of walnut fields. It was almost a complete town, with ranch buildings and offices.  One could ride the Sacramento Northern Railroad from Oakland, through Moraga , Walnut Creek, Sacramento, to Chico.
