Implementation activities
In the design of the rain garden, ‘water is channeled through a series of gullies to each orange tree set within the cobbled patio’ (Ref. 8,9); ‘When the rain comes each circle collects rain and filters it through the sand. Once the circle reaches capacity it flows onto the next circle and so on. Only when all are full does the rain water enter the modern drainage system’ (Ref. 11)
Activities are implemented in general for the monument site. As part of the Great Mosque and being a National but also a "World Heritage Site", the rain gardens are protected by laws and many conservation programs towards the Great Mosque are undertaken. For instance: "The Cabildo Cathedral maintains the commitment to watch over the conservation of the Monumental Complex, in collaboration with the competent administrations. In this way, it works tirelessly to maintain the building, spread its heritage values ​​and facilitate its historical interpretation. For this, it counts on multidisciplinary teams of experts who work in accordance with the scientific criteria and the current regulations" (Ref. 7) There is a National of Cultural Conservation Plan to protect cultural property in Spain (Ref.3) , but also a regional "Heritage conservation and restoration programs" through the Strategic Plan for Culture in Andalusia (PECA). (Ref. 4).
