JEDDAH: The Philanthropic Heritage Foundation chaired by Prince Sultan Bin Salman Bin Abdul Aziz has conducted an architectural study on the historic mosque of Jawtha Village in Al-Ahsa governorate, which was built during the time of Prophet Muhammad (pbuh), in preparation for extensive renovations. This is the third mosque built in Islam following the Prophet's Mosque and Quba Mosque in Madina, and is of historical importance. Dr. Zahir Abdul Rahman, Director General of Heritage, said the scientific study is meant to document all aspects of the mosque, including materials used in building its original roof, and the shapes of its ancient doors and windows. On the basis of the results of this study the foundation will determine the most suitable method for the restoration. He said it will be done according to international specifications and standards, to preserve its ancient historic and architectural characteristics.A previous restoration had been completed at the expense of the Jubail and Yanbu Royal Commission. The current restoration plan will see the rebuilding of collapsed parts of the building. Zahir said the mosque is considered one of the most significant features of the Jawtha Village which includes the remains of some of the Prophet's companions (may Allah be pleased with them) who were martyred in the “Ridda Wars” – the Wars of Apostasy. He said the documentation and restoration of the mosque is part of the “National Program for Caring for Ancient Mosques” launched by the Heritage Foundation under the supervision of the Ministry of Islamic Affairs, Endowment, Dawa and Guidance. The first stage of the program saw the restoration of more than 60 mosques of historical value in different parts of the Kingdom. The second stage restoration work has begun and is being funded by the government, private institutions and generous benefactors.
