Outsider-Art Facts

A 43-year-old French postman tripped over a stone on his rural mail round in 1879 and decided to build a palace. Ferdinand Cheval collected stones on his 18-mile route for 33 years - first in his pockets, then a basket, then a wheelbarrow. Neighbors called him insane. He carved into the wall: 10,000 days, 93,000 hours of struggle. 170,000 people a year now pay to see it.

Leonard Knight arrived in the California desert in 1984 with no art training and no plan - only a message: God is Love. He spent 27 years alone, hand-painting a 50-foot adobe mountain with over 100,000 gallons of donated paint. He slept in a truck at its base, with no electricity or running water. A US Senator called it a national treasure.
