5. Greek Theatre, Los Angeles
The visionary behind the Greek was one Griffith J. Griffith, who had made his fortune in gold mines and, in 1896, donated 3,000 acres of his own land to the City of Los Angeles for public parks. When he died, he passed on a $1 million trust and stipulated that a classic theatre with authentic Greek columns be built on the same land. Since the Greek started hosting concerts in the Seventies, that classy architectural touch has added a dash of drama to shows by everyone from the Who to the White Stripes, Paul McCartney to Paul Simon.
Fun Fact: During World War II, the Greek functioned as a military barracks.
