Originally, the Puerta de Almodóvar (Almodovar Gate), also known as the Walnut Tree Gate (Bad-al-Chawz), is Arabic. The gate was largely rebuilt in the Christian era, underwent a major reform in the sixteenth century, and was restored in 1802 and in the 1960s. It is the only surviving example after the city walls and gates were systematically destroyed at the end of the 18th century, as a result of the demographic increasing the city experienced after three centuries.One stretch of wall has been preserved intact, going on from the gate to the Campo Santo de los Martires, along the Kairuan street. This wall was deeply reformed in the 14th century, and underwent a major restoration in the 1960s by José Rebollo, who added the moat and the lower walkway around it, as well as opening up the gateway at the southern end known as Puerta de la Luna.
