About 20 km from Madrid is the small town of Mejorada del Campo.
If you look carefully, you will notice the columns are old petrol drums.
The project began more than fifty years ago in 1961.
Its initiator, Don Justo, is now ninety-one years old.
He then decided that he would serve god in which own way, by building a cathedral.
What he knew, he learned from books and by consulting photos of cathedrals and other famous buildings.
Sometimes he would consult an expert at his own expense.
The cathedral gained fame when it was featured in a Spanish TV commercial, about a decade ago.
Since then, it has been drawing a steady stream of visitors.
Don Justo says the cathedral is nearly three-fourth finished.
He has already dedicated the cathedral to the Virgin Mary and has named it Nuestra Senora del Pilar.
