For the 2000 World Junior Championships in Athletics, the installation of individual seats was required, which reduced capacity to 66,000 spectators. This requirement ensured that the stadium could not exceed capacity, as seen with the visit of Pope John Paul II in 1987 (believed to be attended by more than 90,000 people, though no accurate measurement could be taken as attendance was free, with no control), or the closing of the Telethon. The official capacity of the stadium as of 2014 is 48,665.
