Historic centre of Gallur Monument · Gallur, Ribera Alta del Ebro, Zaragoza Image of Gallur, not of the place itself. The historic centre of Gallur preserves the memory of the town through which, in the 20th century, the narrow-gauge railway to Sádaba ran — now partly converted into a greenway — and whose fertile lowlands produce the white asparagus typical of the Ribera Alta del Ebro.
