Gates of Hausa kingdoms are gates (Hausa: kofa) or walls (ganuwa) that formerly enclosed Hausa kingdoms. In ancient times, each kingdom was enclosed with a wall that contained various gates. During battles, the gates were closed as a war strategy. Each gate has a name and a gatekeeper (Sarkin Kofa, lit. "King of the Gate"). In the past, especially at night, the gatekeeper was in charge of a single gate at all time. All of the gates are assigned to a single person today.
