Man discovers hidden WWII air raid shelter under his driveway. Simon Marks,
37, found it while trying to park his car and hearing strange noises.
The cracked pavers revealed a piece of metal. He called his father,
and they uncovered an old rusty ladder leading to the shelter.
They learned it was built during WWII for protection from bombings.
Marks plans to restore the shelter as a historical monument. His story went viral after sharing photos.
