The Alhambra and the Generalife have organized a day packed with activities on 18 April, International Day for Monuments and Sites. There will be free guided visits throughout different parts of the World Heritage site, famous for its breathtaking Islamic art and architecture.
Several sections of the site which usually remain closed will be opened to the public to celebrate this special day. They will include los Albercones and las Torres de Siete Suelos. Places are limited so reservations will be needed. You can find more information here
