The Plan for Greater Baghdad was a project done by American architect Frank Lloyd Wright for a cultural center, opera house, and university on the outskirts of Baghdad, Iraq, in 1957-58. The most thoroughly developed aspects of the plan were the opera house, which would have been built on an island in the middle of the Tigris together with museums and a towering gilded statue of Harun al-Rashid, and the university. Due to the 1958 collapse of the Hashemite monarchy, development of the project stopped, and it was never built.
Wright was among the many elite Western architects invited to Iraq as part of a campaign to modernize the capital city. Wright distinguished himself from this group by developing a plan making specific reference to Iraqi history and culture. For Wright, the plan was one of a handful of grandiose, outsize designs produced in the later part of his career.
In the 1950s, Iraq was awash with new oil money. The deal negotiated in the first years of the decade with the Western-controlled Iraq Petroleum Company, which held a monopoly on oil exploration and development, increased the government's share of revenues substantially. Some of this money was dedicated to the construction of new public buildings in Baghdad. As the government, headed by King Faisal II, developed a general scheme for the capital, it determined to call upon world-famous architects—mostly Westerners—to participate in the modernization of the city. The decision was a break with the city's long-established traditional forms, as the architects selected were among the titans of modern architecture and were intended to build within that aesthetic.
Numerous prominent Western architects were invited to Iraq on government commission, including Walter Gropius, Le Corbusier, Oscar Niemeyer, and Wright. Wright received a commission for an opera house in January 1957 and accepted it before the end of the month. He visited the city in May. Originally, the commission called for the opera house to be built on a site in the center of the city. On his visit, Wright instead selected an island in the middle of the Tigris as his site; the area was at the time undeveloped as only recent flood-control measures had made it suitable for construction. With this larger site available to him, Wright was free to develop a plan for not simply an opera house but a full cultural center. After returning to his studio at Taliesin, he developed a concept for a university on the left bank of the Tigris. (Ultimately, the university plan used was one by Gropius, which exists today.)
