As of May 2006, the plaza includes a stage, metal arches over the crowd area, and a monument of 138 flags. The stage and arches have been up since before a May 2005 concert by the American rock band Audioslave, which the band claims was the first outdoor rock and roll concert on Cuban soil by an American band. The capacity of the plaza was an impressive 60,000 for that free concert, but the specifics as to the setup for each event are unknown.
