Secret passages, or hidden routes used for stealthy travel, escape, or movement of people and goods, are commonly seen in movies, especially ones that involve James Bond. However, this clever engineer decided to build a hidden entry to their basement directly into the floor of the patio deck. This would most certainly come in handy if your have a horde of zombies chasing after you, or just want quick access to a secure location.
Hidden passages have existed since ancient times, as builders of the Egyptian pyramids utilized secret passages and booby traps to protect the burial chambers from tomb robbers. They even went as far as hiding burial chambers behind statues. One more recent example would be the Regal Knickerbocker, in Chicago, Illinois. This 350-room hotel built in the 1920s boasted a secret door in one of the penthouse ballrooms and was extensively used during the U.S. Prohibition era (1917-1919).
