Carnival of os galos da Merca Activity · A Merca, Terra de Celanova, Ourense Image of A Merca, not of the place itself. Carnival of masks of the concello's own: the galos go through the streets in brightly coloured costumes and with their own rules of play, and they are joined by the mecos of Froxás das Viñas, in one of the variants of the Ourense entroido least known outside the comarca, in a municipality of fewer than two thousand inhabitants.
