The Gateway Arch is a 192 meter high arch designed by Eero Saarinen and built in the city of St. Louis, USA. On the morning of October 28, 1965, with the sky clear and at 4°C outside temperature, the last keystone of the arch was placed. The placement of the final piece required the collaboration of firefighters to irrigate the south leg of the arch, which, because of the solar incidence, dilated more than planned. It was also necessary a gigantic hydraulic jack to separate the two legs of the arch a little more than a meter to fit the last part of this masterpiece of engineering and technology of the twentieth century.
