Of the many locations of the Guggenheim Museum, the one housed in the most beautiful building of all is located in Bilbao, Spain. Located on the Nervion River, the structure of Frank Gehry’s design features his usual bold curves, metal shingles, and stunning windows. The beauty of the building is doubled in its reflection in the water below. The beautiful color is partially due to the treatment of the metal and also the use of limestone as a building material. Frank Gehry’s designs have been spread around the world because their beauty is something that everyone can appreciate.
