Site information:

2734 Calhoun St, Old Town, San Diego (this is the address given by OHP - I believe the correct location is San Diego Ave, near Telegraph Way)

32.754633,-117.197954

There are four Casas with the name "Machado" attached to them in Old Town. One is the Casa de Machado y Stewart, which is landmark #73. It is somewhat unclear which of the other three Machado casas this landmark (#71) is intended for. However, all the information I have found indicates the Machado y Silvas home is the correct adobe, including the fact that the park sign indicates it was dedicated as a CHL in 1932.

The address given by the OHP above is for a Juan Machado house (not Jose Manuel), and does not seem to be the correct one.  I took photos of all of them.

Photos 1-2 are of the Machado y Silvas casa, photos 3-4 are of the Machado y Worthington casa, and 5-7 are of the Casa de Machado site, which is now a restaurant. All sites are located on Old Town Plaza.

Plaque information:

No plaque, but there are informational signs.
