The village of Belchite is a monument to the Spanish Civil War, which took place between 1936 and 1939. It's been left as it was and is a unique place to visit in Spain, surrounded by low hills. The ghost town has shell-shattered ruins and an old village church which is open to the public and collapsible buildings roped off.
