"... its walls ... are of Moorish origin (11th century) and have been restored in the 15th century." Wikipedia. And you can see the very obvious Aabic style on the inner gate and a major strengthening of this gate in the outer defences from the 15th century. So not a restoration as such, more a complete defensive upgrade!
