Frank Lloyd Wright designed the Ennis House, which was constructed in 1924. With it's strange, Mayan temple-like appearance, the house sits on a narrow ridge-top above Los Angeles, and not far from the Griffith Park Observatory. It's one of four concrete block (or "textile block") houses in Los Angeles that Wright designed, and it's the most monumental.
I like this photograph for a couple of reasons. One, it's an unusual building, sitting in the middle of a street lined with more contemporary - and far smaller - homes. Two, I had to work to make this photograph, since I chose to ride my bike to the Ennis House, which sits several hundred feet up in the Santa Monica Mountains. It was worth the effort, with the weather, light, and my lungs and legs all cooperating with me.
