Festivities of invierno de Gallur Activity · Gallur, Ribera Alta del Ebro, Zaragoza Image of Gallur, not of the place itself. Gallur's winter festival is held in the town that in 1209 the king of Aragón handed over as security for a loan to the Navarrese monarch; its fertile valley, irrigated by the Canal Imperial, produces the white asparagus typical of the region.
