As a result of its construction boom during the 1920s and 1930s, Shanghai has among the most Art Deco buildings in the world. One of the most famous architects working in Shanghai was László Hudec, a Hungarian-Slovak who lived in the city between 1918 and 1947. His most notable Art Deco buildings include the Park Hotel, the Grand Theatre, and the Paramount. Other prominent architects who contributed to the Art Deco style are Clement Palmer and Arthur Turner, who together designed the Peace Hotel, the Metropole Hotel, and the Broadway Mansions; and Austrian architect GH Gonda, who designed the Capitol Theater. The Bund has been revitalized several times. The first was in 1986, with a new promenade by the Dutch architect Paulus Snoeren. The second was before the 2010 Expo, which includes restoration of the century-old Waibaidu Bridge and reconfiguration of traffic flow.
