Look at this crazy building!
It was built by Ferdinand Cheval who was a French postman who spent 33 years of his life building it. He called it the Ideal Palace.
He started in 1879 when he started collecting stones to use in the building and often worked at night by the light of an oil lamp.
The outer wall took him 20 years to build and the palace is a strange mix of styles from Christian to Hindu mythology.
Ferdinand died a year after completion.
