<P> A sally port is a secure , controlled entryway to a fortification or prison . The entrance is usually protected by some means , such as a fixed wall on the outside , parallel to the door -- which must be circumvented to enter and prevents direct enemy fire from a distance . It may include two sets of doors that can be barred independently to further delay enemy penetration . </P>
