The UN officially began on October 24, 1945, and in December 1946 John D. Rockefeller Jr., who had paid for this riverfront land, donated it to the organization. A board of architects, with final designs by Oscar Niemeyer and Le Corbusier, began work in 1947; construction started in 1948, the UN moved into the Secretariat Building in 1951, and the complex was declared complete in 1952. Visitors enter at First Avenue and 46th Street for guided tours of the complex.
