For 53 years, Justo Gallego has been building a cathedral by hand on the outskirts of Madrid almost entirely by himself. Gallego has no formal architecture or construction training, but that hasn't stopped him from toiling on this herculean task. At 90 years old, Gallego knows that he will not be able to finish the project in his lifetime. But he keeps at it anyway, day after day, driven by his faith.
