exhibition, the rest of the arch was constructed from wooden panels. In the following years, the monument's completion was the topic of a continuous battle between King Leopold II and the Belgian Government, which did not want to spend the money required to complete it. The park was also one of the sites of the Brussels International Exposition of 1897, for which the existing buildings' wings were extended, although the arch was still incomplete. The original architect was Gédéon Bordiau, who spent close to twenty years on the project. The structures were built in iron, glass and stone, symbolising Belgium's economic and industrial performance. The construction of buildings was put on hold in 1890 for lack of funds, and was eventually stopped by the architect's death in 1904. His successor, chosen by Leopold II, was the French architect Charles Girault. Girault changed the design from a single to a triple arch, and began a course of round-the-clock construction in a final push to complete it. The original pavilions of the 1880 exhibition, designed by Bordiau, were largely replaced with the arcade designed by Girault in 1904 and the large halls on both sides. Only the glass-constructed Bordiau halls remain from the 1880 structures. The monument was completed with private funding in May 1905 and the arcade was inaugurated by Leopold II on 27 September 1905, just in time for the 75th anniversary of Belgian Independence. The triumphal arch that had already been planned was amended and expanded to meet the king's wishes. A fire destroyed the south wing of the complex in 1946, part of the Royal Museums of Art and History (RMAH). The collection pieces were saved, and the burnt wing has since been rebuilt. As for the north wing, home to the Royal Museum of the Armed Forces and Military History, it was spared. Current tenants and usage Nowadays, the various buildings of the Cinquantenaire complex host three museums: the Royal Museum of the Armed Forces and of Military History, which has been the sole tenant of the northern half of the complex since 1880; the Art & History Museum (formerly called the Cinquantenaire Museum), which has occupied its southern half since 1889; and Autoworld vintage car museum. In addition, the north-western corner of the park is the location of the Great Mosque of Brussels (1978), as well as two monuments: the Temple of Human Passions (1896), and
