Heritage campaigners and many locals have looked on aghast as the historic sections of Mecca and Medina have been bulldozed to make way for shopping centres, hotels and skyscrapers. The Washington-based Gulf Institute estimates that 95 per cent of the 1000-year-old buildings in the two cities have been destroyed in the past 20 years.
In Mecca, the authorities destroyed the Ottoman era Ajyad Fortress and the hill it stood on. Other historic sites lost include the Prophet's birthplace - now a library. Of the seven ancient mosques built to commemorate the Battle of the Trench - a key moment in Islam - only two remain.
The disregard for Islam's early history is partly explained by the regime's adoption of Wahabism, an austere and uncompromising interpretation of Islam that is vehemently opposed to anything which might encourage Muslims towards idol worship.
