When this acoustically perfect performance hall opened in Bunker Hill in 2003, it became an instantly recognizable architectural landmark, not just in Southern California, but around the world. And yet sitting quietly on the roof of this modern masterpiece is a sanctuary most people have never even heard of. The Blue Ribbon Garden is an oasis filled with sculptures, ponds, mosaics, and a garden of edible flowers in case you get hungry. With over an acre of land, there’s plenty of room to ponder one’s greatest ideas. No outlets or wifi here.
