The Great Mosque of CÃ³rdoba, was for centuries a symbol of diversity and tolerance in the southern Spanish city and has long been one of Europe's most admired historical monuments.
But recently, disagreements over its management and efforts by the Catholic Church to take it out of public hands have made it the subject of a fierce dispute.
Sitting on the shore of the Guadalquivir river, the Great Mosque has long been revered not just as a remarkable piece of architecture, but also one with a unique history.
The caliph of Damascus constructed the huge mosque on top of a Visigothic church in the eighth century, ushering in a period of intense intellectual and cultural activity in CÃ³rdoba.
When Christian forces reconquered the city in the 13th century, they built a cathedral in the centre of the mosque as a symbol of the restoration of the Catholic faith.
Today, visitors can wander through dozens of the mosque's horseshoe arches before reaching the cathedral, where Mass is still held. Only Christians are allowed to use the cathedral-mosque as a place of worship.
However, it has emerged that the local archbishopric is in the process of registering itself as the owner of the entire building - which is public property - a move that will be irreversible by 2016. Many in the city believe this is part of an effort by the CÃ³rdoba Catholic authorities to suppress the monument's Islamic identity.
âThe Great Mosque is a global symbol of the meeting of cultures and today more than ever the world needs symbols like this,â said Antonio Manuel RodrÃguez, a professor of civil law at the University of CÃ³rdoba.
He sparked a furore recently when, during a conference, he accused the CÃ³rdoba archbishopric of jeopardising this symbolism by attempting to appropriate the property.
Prof RodrÃguez said a loophole in land ownership laws dating from the dictatorship of Francisco Franco was being exploited and that the archbishopric was âadministrating the monument in an abusive wayâ.
He warned that the historic centre of CÃ³rdoba even risked losing its status as a Unesco World Heritage Site if the âChristianisationâ of the Mezquita continued.
The prospect of the building becoming the property of the Catholic Church has also upset Muslims, ince it is still an important Islamic symbol around the world.
âIt's a historical heritage belonging to all Spaniards,â said Isabel Romero, director of the Islamic Junta, which represents Muslims in Spain. âIt's very strange that it should pass into private hands.â
Ms Romero said this was the latest of many efforts by the church, which manages the Mezquita, to eliminate the building's Muslim identity.
In 2010, the archbishop of CÃ³rdoba, Demetrio FernÃ¡ndez, publicly called for the word âmosqueâ to be removed from tourist- related references to the building, âto avoid confusing visitorsâ, a request that has been obeyed. Tourism brochures describe it as âCÃ³rdoba Cathedralâ. Its website address contains the word âcathedralâ, but not the word âmosqueâ.
âAny attempt to wipe out the identity of the Great Mosque is an attack on us Muslims,â Ms Romero said.
Six days ago, a petition to "Save the Great Mosque Cordoba" was initiated on the website ipetitions. It is seeking a goal of 10,000 signatures.
Ãngel Luis GonzÃ¡lez (20), a practising Catholic from the city who regularly takes Mass in the building, said it made sense for the church to take control of the building, âbecause it spent more time as a cathedral than as a mosqueâ.
âI call it a cathedral' because I'm a Catholic and I pray in a cathedral, not in a mosque,â he said.
All of this is a far cry from the period when CÃ³rdoba was a beacon of multi-faith tolerance, with Muslims living peacefully alongside Jews and Christians.
Yet the Great Mosque has seen controversy before. In 2010, two Austrian Muslims were arrested there after grappling with security guards who had stopped them from praying.
In the early 1970s, Franco considered a plan to âtransplantâ the cathedral brick by brick to another city, reportedly with financing from the Saudi royal family, to separate the Catholic and Muslim temples.
The archbishop of CÃ³rdoba at the time vetoed the project.
Spain has a resident population of 1.3 million Muslims, a third of whom are Spanish nationals.
