The city hall, built in 1928, was the tallest building on the West Coast and remained for more than 20 years. The main building materials are all sourced from California's local soil and water sources. The tower design at the top of the city hall follows the Mausoleum of Mossolas in the seven wonders of the ancient world, which also makes the municipal building unique and a location for many Hollywood movies, including the household movie Superman. The city of Los Angeles is not as heavily guarded and inaccessible as elsewhere. The ball-shaped hall on the first floor of the government and some office areas and meeting rooms are free to the public. The state government press conference site is also accessible, of course, and it all needs to be accompanied by staff. If you are interested in the American regime, want to know the mode of operation of the state government or just want to visit the internal structure of the government. Los Angeles City Hall is not to be missed.
