About this event
Lisbon's flagship free classical festival, run by the São Carlos National Theatre, has moved to the open square at the Centro Cultural de Belém for its eighteenth edition. Opera in concert, symphonic programmes and ballet come out of the opera house and onto an outdoor stage, performed by the Portuguese Symphony Orchestra, the São Carlos choir and the National Ballet Company for an audience in deckchairs.
Why we picked it
World-class opera and ballet at no cost, in the open air, with the final nights landing inside the priority week.
Free entry
The organiser states the festival keeps 'entirely free access'; entry is free but subject to the capacity of the square.
