The raising of the Mayo of Casarrubuelos Activity · Casarrubuelos, Comarca Sur, Madrid Image of Casarrubuelos, not of the place itself. Every 1 May the young men bring a poplar some thirty metres tall from the riverside grove, fit its crown on and raise it in the square in honour of the Most Holy Christ of the Vera Cruz; the maypole stays up until the end of the month.
