In American states where the plains and the prairies dominate the landscape, you cannot avoid the silos and the elevators, most of which lie beside the railroads so grain can be transported easily and quickly. Often the largest buildings in the locality, even when surrounded by what qualifies locally as a town or a small city, the silos and the elevators have an austere beauty all of their own, not least when passed by one of the many mile-long freight trains that criss-cross the continent. The silos and the elevators in the photos below are in South Dakota, North Dakota, Nebraska and Montana.
During a recent trip to Spain, I saw silos and elevators smaller but not dissimilar to those on the American plains and prairies. Most such silos and elevators exist along the railway lines of Andalucia and Extremadura.
