The Casa de la Marquesa is one of Gandia's old noble houses, and for a few weeks each spring its courtyard turns into a small concert stage. Six shows make up the season, running from late April to the close of June. Two of them, Bèrnia and Colectivo Panamera, are free; the other four are ticketed, at around EUR 10 if you book ahead or EUR 15 on the door. There's a season pass too, EUR 36 for the lot, with a cheaper rate for younger and older folk.
It's a modest, open-air setting rather than a big festival, which is rather the point. You sit close, the walls hold the sound, and the line-up leans towards Spanish acts across a mix of styles. Tickets go through the venue box office or VivaTicket.
