Elks Lodge No. 99 / Park Plaza Hotel (1930/2009)
Looking at the Elks Lodge from the south side of the building and the west edge of MacArthur Park. The building is from 1925 and by architect Claud Beelman. If you are lucky, there will be a nice guard who will let you in and look around. The interior is as spectacular as the exterior.
