The Grec Festival of Barcelona is an international theatre, dance, music and circus festival. Over the course of its history, the festival has become not only the major summer attraction in Barcelona, but also a reference on the European performing arts calendar.

The Grec Festival is promoted by Barcelona City Council, but no other public administrations are involved; rather, the shows are organised and produced by a large number of private sector theatre impresarios and promoters.

The festival takes its name from of its main venue: an open-air theatre (the Teatre Grec) built on Mount Montjuïc for the 1929 Universal Exhibition. At first, this “Greek Theatre” was the only venue used for festival productions, but, today, the Grec programme embraces many other theatres, cultural facilities and public spaces all over the city of Barcelona.
