Karnak Great Hypostyle Hall, Luxor, Egypt — Built under Seti I and Ramesses II, this forest of 134 columns arranged in 16 rows covers an area larger than Notre-Dame Cathedral in Paris. The columns supporting the central nave rise 21 meters tall; their original painted surfaces still retain traces of the vivid pigments applied 3,200 years ago.
