Since 1963, a man named Justo Gallego has dedicated his life to building a cathedral on the outskirts of Madrid almost entirely by himself. Despite the lack of any formal training in construction or architecture, Gallego has continued work on the giant church into his 90s and works on it even today. Driven solely by his faith, he admits the project will never be finished in his lifetime and he has yet to make plans for what happens after he dies. Great Big Story gives us a quick glimpse of this unusual man and his towering cathedral.
