Save Our Heritage Organisation, SOHO, is a private, member-based 501c3 non-profit formed in 1969. Based in Old Town San Diego, the birthplace of California, we manage and operate historic sites and resources throughout San Diego County. We are the only countywide historic preservation organization, in a county that encompasses 18 incorporated cities and numerous neighborhoods and communities. SOHO works on a wide range of preservation issues throughout San Diego County. All our advocacy efforts share a common goal: to protect and preserve the historic architectural and cultural resources of our region.
