The de Young is a fine arts museum located in San Francisco’s Golden Gate Park. The building was completed by architects Jacques Herzog, Pierre de Meuron and Fong + Chan and opened on October 15, 2005. The terrain and seismic activity in San Francisco posed a challenge for the designers. To help withstand future earthquakes, the building can move up to three feet (91 centimeters) due to a system of ball-bearing sliding plates and viscous fluid dampers that absorb kinetic energy and convert it to heat.The entire exterior is clad in 163,118 sq ft (15,154.2 m2) of copper, which is expected to eventually oxidize and take on a greenish tone and a distinct texture to echo the nearby eucalyptus trees. In order to further harmonize with the surroundings, shapes were cut into the top to reveal gardens and courtyards where 48 trees had been planted, the giant tree-ferns that form a backdrop for the museum entrance are particularly dramatic. The building is clad with variably perforated and dimpled copper plates, whose patina will slowly change through exposure to the elements. The twisting 144 foot (44 m) tall tower is a distinctive feature, and can be seen rising above the canopy of Golden Gate Park from many areas of San Francisco.
