The Arab Walls are by far Madrid's oldest defensive walls. They were built by Muslims in the 9th century, making them the oldest remains of the Arab walls in Spain. In 1954 they were recognized as a historical and artistic monument. They were restored and then made available to visitors in 1987. Along with the walls, an adjacent park named El Emir Mohamed I was also made available, named after the Cordoba emir, founder of Madrid.
The first walls in Spain were built by early medieval Muslim rulers at a time when the Moors dominated the Iberian Peninsula. Madrid's walls defended the Muslim citadel (also called almudaina) Mayrit. It was also the first name of the current Spanish capital. In the summer, musical and theater performances are organized in the vicinity of this monument.
