In the area around the Museu Nacional d'Art de Catalunya site, moreover, many of the buildings erected for the 1929 International Exhibition remain, whilst others have also been established. All these different elements form a complex that has become one of the most attractive cultural, commercial and leisure centres in the city. The outstanding buildings dating from the time of the International Exhibition include the pavilions housing the Barcelona Trade Fair (Fira de Barcelona), the Estadi Olímpic Lluís Companys, refurbished for the 1992 Games, the Poble Espanyol and the Teatre Grec, a Greek amphitheatre built in a disused quarry. This gives its name to Barcelona's summer arts festival (GREC).
