Built in 1928, the 27-story Los Angeles City Hall was the tallest building in the city for more than 30 years. The structure's distinctive ziggurat tower was designed to resemble the Mausoleum at Halicarnassus, one of the seven wonders of the ancient world. The building has been featured in numerous films and television shows, but it is probably best known as the headquarters of the Daily Planet in the Superman TV series (or from Beverly Hills Cop, depending on your birth date). When it was built, City Hall was the sole exception to an ordinance outlawing buildings taller than 150 feet. While you're here, be sure to take the elevator to the rarely used 27th-floor Observation Deck -- on a clear day (yeah, right), you can see to Mount Wilson 15 miles away. Free docent-led tours are available at 10am to noon Monday through Thursday, and self-guided tours are available at other times. Call tel. 213/978-1995 for tour information.
