Introduction to the Los Angeles City Hall: The Los Angeles City Hall was built in 1927 with a height of 138.4 meters and 28 floors. The top of the city hall is designed to imitate the Mausoleum of Mausolus from the Seven Wonders of the Ancient World. The building materials are from The sandy soil of California's 58 counties and the water of 21 missions. City Hall looks dwarfed by modern skyscrapers. But its majestic towers remain Los Angeles' most familiar landmark. The internal dome hall has a magnetic vault and excellent acoustics. The vault is decorated with eight figures, representing the municipal government's concerns for education, health, law, art, service, government, protection and trust. The City Hall is located at 200 North Hot Spring Street.
