Frequently Asked Questions
It is most commonly written as two words ('sally port'), though the hyphenated form 'sally-port' is also historically seen.
No. While originating in medieval fortifications, the term is still used for secure entry systems in modern prisons, military bases, and banks.
A main gate is the primary, often large and visible entrance. A sally port is typically smaller, more defensible, and designed for controlled, often surprise, exit and entry of personnel.
Yes. 'To sally forth' or 'to sally out' means to set out boldly or to rush out suddenly, especially from a defensive position. This is the verb from which 'sally port' derives.
