Former Hollywood Lodge No. 355, now the El Capitan Theater.
I came across an article from 2014 on the Curbed LA website, 7 of LA's Most Magnificent Examples of Masonic Architecture by Pauline O'Connor, that points out seven of the more notable Masonic structures in the Los Angeles area. So if you are ever in the region with some time to kill (and you'll need it - traffic hasn't improved since I lived there), go and visit these beautiful locations. One update from the article is that the unique Masonic Temple in North Hollywood was unfortunately sold last year, but will be developed.

Down the road a bit is Burbank Lodge, where I had the distinct pleasure of speaking last year. I heartily encourage you to visit them as well. See their website here.
Los Angeles Lodge No. 42, which was chartered in 1853, and was the first lodge in LA, as well as the second oldest in Southern California. Their original building can be seen in the historic area known as El Pueblo de Los Angeles (right). They now meet across town in the Santa Monica Masonic Center.
