It has become one of the main summer attractions in the city and a point of reference on the European performing arts calendar.

The event takes its name from the festival's central venue: an outdoor amphitheatre (the Teatre Grec) built for the 1929 Universal Exposition on Montjuïc mountain. This was originally going to be the festival's sole venue, but these days the Grec involves many other locations.

The Grec is promoted by Barcelona City Council, however it doesn't just involve the public administration, but also a number of theatres and private promoters who co-produce events with the festival.

The Grec's mission is twofold: it presents the best creative work from Catalan artists and groups, which it supports by producing the shows they perform during the summer; and every year it puts on the most interesting artistic creations from the rest of Spain and the whole world.

In 2013, the festival had a total of 120,000 spectators, who were able to choose from 66 different shows
