The forum was also politically useful, given the mayor's earlier failure to deliver on a 1996 promise to secure an international exposition for the city.
The official aims of the 2004 Universal Forum of Cultures included support for peace, sustainable development, human rights and respect for diversity.
The forum hosted more than 40 international conventions (participants included Juan Antonio Samaranch, Mikhail Gorbachev, José Saramago, Felipe González, Rigoberta Menchú, Angelina Jolie, Robert McNamara, Valéry Giscard d'Estaing, Lionel Jospin, Luiz Inácio Lula da Silva, Romano Prodi and Salman Rushdie, among others), performances, markets, games, 423 concerts, 57 street performances, 44 theatre, dance and cabaret companies, 20 circus acts and over 20 exhibitions.
The new site comprises a convention center, central plaza, parks, auditoriums, a new port and a Forum Building (designed by architectural firm Herzog & de Meuron).
The forum showed four thematic exhibitions, intended to achieve a renewal of ideas and attitudes toward the 21st century, by undertaking a careful analysis of cultural diversity, sustainable development and the conditions for peace: The central plaza and the open space surrounding forms a public area called Parc del Fòrum, and is now home to several massive events around the year, including the Primavera Sound Festival, Summercase, the Catalonia April Fair and the most popular concerts in La Mercè.
