The 16th Avenue Tiled Steps, colloquially known as the Moraga Steps, is a stairway in the Golden Gate Heights neighborhood in San Francisco, California. Fodor's calls it "possibly the world's largest mosaic staircase", and it leads up to Grandview Park. The flight contains 163 steps stretching 90 feet high. These steps are also covered in over 2,000 unique tiles from over 75,000 glass fragments.
