When you visit Coit Tower, spend some time looking at the murals surrounding the hallway inside the structure. At first glance, you may just bypass them and concentrate on the views and getting into the elevator, but the murals themselves are an amazing attraction. Created in 1933 as one of the first public works projects, the California School of Fine Arts faculty and staff worked hard to create paintings that would reflect life in California. There are cowboys, 49ers, fruit pickers, industrial workers, etc.
During this time, Rockefeller Center removed Diego Rivera's artwork because he had painted in an image of Lenin. The artists who were working on Coit Tower protested and painted in several leftist images to show solidarity with Rivera. These paintings created quite a stir, and one of the pictures entitled "Workers of the World Unite" was removed before the opening.
Today, you can still see the socialist influence in the murals that line the hallways of Coit Tower. You can see it in the man who is pulling Karl Marx's Das Kapital off a bookshelf, or the man who is portrayed reading a newspaper with the headline talking about Rivera's artwork being removed from Rockefeller Center. It is also in the painting of a man who is reaching for the Daily Worker from a newsstand, and in the scene of a poor family panning for gold as a rich family looks on. In addition, closely check out the industrial paintings, especially the one showing a sea of diverse workmen joining together.
It is definitely worth going to Coit Tower for the phenomenal views, but also take some time to really study the murals. You won't be disappointed.
