Hobart building is one of the landmarks of downtown San Francisco. It was designed by Willis Polk (in 1914) and definitely it is his masterpiece. What makes this building very unique these days is that part of it (the front and top floors on all sides) is highly decorated in Renaissance and Baroque style, wheres the "back" of the building is completely plain, boring and undecorated! This is due to the fact that when the Hobart building was built, there was another building adjacent to it. Unfortunately, when that building got destroyed, nothing was done to decorate the exposed wall...
