Arco del Portillo is a 14th-century horseshoe arch in Córdoba that functioned as a defensive gateway closed each night to protect city inhabitants. Located on Calle San Fernando opposite the San Francisco church, this simple but strategic opening connected the old Medina to the walled Axerquía district, serving as the boundary between two distinct urban quarters. Also known as the Arch of San Francisco or Portillo del Corbache, its basic horseshoe form features minimal decoration yet represents important medieval urban planning and fortification. Declared a cultural monument in 1931, it underwent critical consolidation work in 2020 after decades of structural threat following an adjacent building's demolition.
