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.

Architectural concept 
In Hausa Kingdoms, gates were built from mud, dried grass, timber, metals, stones and other traditional building materials suitable for the building. The gates are designed based on Hausa culture and depict Hausa traditional architecture using burn bricks and traditional colors of the Hausa region. On average, the gates reach a height of about five meters with a length of about ten meters. They are illustrated with patterns, marks, symbols and Hausa design, such as a tambarin arewa, a logo frequently used in Hausa buildings which serves as an emblem or flag to Hausa people. When the structure of the gate is completed, the entire gate is painted in a traditional style while some gates are left brownish with the natural color of mud, like the Gate of Marusa in Katsina.

Overview 
In ancient times, every gate was allocated to one person. It is his duty at all times to protect and maintain it by providing administrative records of every movement of people passing through the gate along with foreign record affairs for self-defense. Every gate has a key for opening and closing; the keys are allocated to Sarkin Kofa. Usually, there is a fixed time for closing and opening of every gate but today the gates are open without the need for keys. Traditionally, during wartime, orders only came from either the emir of the kingdom or his war counselor, the Sarkin yaki'. Out of wartime, orders and control of the gate are left to the Sarkin Kofa. It is an order that entry into the city may only be done through those gates. When the gates are closed at night, they do not reopen until dawn. The post of Sarkin Kofa is inherited generationally in the Hausa Kingdom, from a Sarkin Kofa to his children. The gates also serve as a tourist attraction nowadays in Hausalands.

 Gate of Kwaura: The gate was named after a prominent warrior of Rimi who was given the ruling title of "Kwauran Katsina", which was transferred to the gate.
 Gate of Kwaya: This Gate derives its name from an emir of Habe called Sarkin Kwaya who ruled a small town called Kwaya, which is south of Katsina. The duty of this ruler is to provide grain to the emir of Katsina like guinea corn, millet, and maize for the emir's estate. It was said that it is through this gate Wali Jodoma was expelled from Katsina by the emir, so he went passed through the gate, turned around and cursed it, saying "Nothing good will be done on this Gate unless 500 years have passed". People built houses near every gate in Katsina except the Gate of Kwaya. The gate is now one of the major gates into Katsina from various cities. Shararar Fayif and Sabuwar Unguwa are close to this gate.
 Gate of Durbi: This gate, according to the first source, derived its name from the emirate of Durbi of Kusheyi. The gate derived the name when the Durbawa began ruling the emirate of Katsina. When they migrated to Katsina from their town, the emirate of Durbi changed its name to Durbi-Katsina. The ruler of the emirate of Durbi was called the "Hakimin Katsina". Durbi has been in Mani since Durbi Saddiku's rule from around 1810-1835. There were also other Durbi emirs, such as Durbi Fandiku who ruled from 1836-1860, Durbi Gidado (1860-1883), and Durbi Dikko (1891-1906). The Durbawa entered through the gate when they arrived at Katsina.  The gate was then called the Gate of Durbi, meaning the Gate of emirs from Durbi. This gate is closed to towns like Filin Samji and Rimin Badawa.
The Gate of Guga: This gate has three original names: it was called the Gate of Yammawa because it is located east of Katsina; the Gate of Tsaro, which means "gate of security" because soldiers were posted at the gate to prevent sudden attacks; it was mainly known as the Gate of Guga, the word "Guga" coming from a wife of Sarkin Gobir known as Bawa Jan Gwarzo. She ran away from her husband to Katsina through this gate, to warn the king of Katsina known as Muhammadu Jan Hazo (ruled from 1740-1751) for her husband's preparations to attack Katsina. After defeating the Gobir kingdom, the emir renamed this Gate to honor her loyalty.
 Gate of Sauri: This is a gate in the northwest sector of Katsina, which is close to Unguwar Rafukka, Nasarawa, Makera, and Yammawa. The gate of Sauri has two sources about its origin: according to the first source, Kofar Sauri derives its name from Sarkin Samari, who stays close to the gate. At first, the name "Samari" was given to the gate before it mutated into "Samri", then "Sauri". According to the second source, its name came from the regime of Sarki Ummarun Dallaje (1807-1835)  when a warlord called Danbaskore lead a counterattack against the city of Katsina. when he discovered all the gates were closed, the emir of the Sauri town "Sarkin Sauri" (now Kaita), who was an ally to the Katsina, intercepted Danboskore and defeated him. When he emerged victorious, he erected a gate in the wall of Katsina, which was named the Gate of Sauri in remembrance of the legend of Sarkin Sauri.
 Gate of Marusa: This gate is considered to be one of the oldest gates in the history of Katsina. It was said to have been built in the 15th century. It was built together with the wall of Katsina, and derives its name from a ruler of Habe called Marusa Usman who ruled Dutsi. He was said to be a warrior who entered and exited Katsina through this gate from Dutsi. Another source says it was from a man who specialized in catching slaves.
 Gate of Yan daka: It was said to be built around 15th century. The gate Yan Daka derives its name from a ruler in Dustin Ma, who was given the post ruling of "Yanɗakan Katsina" in the Katsina emirate. His house was close to the gate.

 Gate of Gayan: This gate was created for the people of Gadar Gayan, to have easy access when entering the city. The word Gayan is derived from a river named Gayan and a town named after the river called Gadar Gayan.
 Gate of Kuyan Bana: This gate was the second to be erected. It derives its name from a warlord of Queen Amina known as Mayaki Kuyan Bana.

 Gate of Kibo: The gate was originally named Kofar Tukur Tukur. The people of Gobir, Zamfara, Yawuri, and Kabi used to enter the city of Zaria from this gate. The gate derived its name from a stone located in a town of Tukur Tukur. Tukur Tukur is an old town outside Zaria; during the reign of Sarkin Zazzau Sambo, a battle took place close to Tukur Tukur alongside the gate. The gate changed its name to the arrow, "Kibo", afterward.
 Gate of Doka: The Gate of Doka was the fifth to be constructed in Zaria. It was originally called the gate of Kano. It is said that it derived its name from a tree that was close to the gate known as "Bishiyan Doka", while another source states the gate derived its name from the gatekeeper known as "Doka".
 Gate of Bai: The place where the gate is erected is at the back of the house of the emir of Zazzau. The word "bai" means behind in Hausa, which means the Gate behind the emir's house. The people of Bauchi usually enter the city through this gate.
 Gate of Jatau: This gate was named Jatau after a prominent king of Habe known as Isiyaku Jatau, who ruled Zazzau from 1782 to 1802.

Maintenance  
The gates were formerly the responsibility of traditional rulers known as emirs who assigned maintenance duties to the Sarkin Kofa. In 1959, the Federal Government of Nigeria declared the gates to be national monuments and the responsibility transferred to the Federal Government. Some gates are falling into disrepair due to lack of maintenance.
