Although it was discovered by Juan Cabrillo in 1542 when looking for the mythical Strait of Anian, San Diego is a young city. To this day, like many other West Coast locations it is considered bereft of “historic” locations; even though Native Americans had lived in its environs and other areas for thousands of years prior to Cabrillo’s arrival. Perhaps this bias springs from the fact that not many people know much about San Diego other than what they learned in Anchorman; or perhaps this bias springs from the fact that while San Diego has historic sites, most of them are not common knowledge. In any event, San Diego is a city with ancient historic sites; and more modern historic sites. It is even a city with lost historic sites. While I’m sure there are plenty of semi-lost; partially-lost, and actually-lost sites out there that I don’t even know about, the best almost-actually lost site I’ve come across and found is this one – the ruin of the Jamul Kiln, or if we’re being technically accurate, the Jamul Cement Works.
