It took me some time to figure out what this building is, or was. Given the styling, I thought perhaps it had been built as an Eastern Rite or Orthodox church.
No, in fact it was a synagogue. This building was the Temple Emanuel Synagogue, built in 1899. I don't know its history beyond that, but today it is an events center and available for various uses.

Of interest, this building strongly resembles the St. Peter and St. Paul Antiochian Orthodox Church in Salt Lake City, which was also originally built as a synagogue.
Observant folks might notice that this post was first made in February 2011, but has now reappeared in November, 2012. The reason is that I happened to be parked in this neighborhood a couple of days ago and had the opportunity to take photographs of this structure from the sidewalk, as opposed to from inside my vehicle, as the first photo was taken.
