Your One Thing to Do in L.A. This Week is, simply put, awe-inspiring. A FREE visit to a place with some of the best views in Los Angeles uncovers one of the greatest Hidden Secrets in the City: a 900-seat auditorium built specifically for one of the largest paintings in the world, 195 feet long and 45 feet tall!! And the story of how it came to L.A. is almost as long as the painting itself, full of tragedy, resurrection, and wonder.
