Other hidden doors are much simpler; a trapdoor hidden under a rug can easily conceal a secret passage. Some buildings have secret areas built into the original plans, such as secret passages in medieval castles. Some medieval castles' secret passages were designed to enable the inhabitants to escape from a siege.

Other castles' secret passages led down to an underground water source, which provided access to drinking water during a prolonged siege. Traditional Arabic houses sometimes have a "Bab Al-Sirr" a secret door used as an emergency exit built into the walls and hidden with a window ledge sill or bookcase. The name comes from one of the six gates cut through an ancient wall in Aden (in modern-day Yemen), which was opened only in the event of a state security emergency. In modern-day Spain, the Arab fortress of Benquerencia had a Bab al-Sirr known as the "Door of Treason."

Other secret passages have sometimes been constructed after the initial construction, particularly secret tunnels. These tunnels have often been created as escape routes from prisons or prisoner-of-war camps, where they are known as escape tunnels. These secret tunnels typically require a hidden opening or door, and may also involve other deceptive construction techniques, such as the construction of a false wall.
