Mecca is the most holy city in Islam. The city is sacred in their beliefs as the first place created on Earth. The Ka’ba, the centre of Islam, is a rectangular building made of bricks. Around the Ka’ba is the great mosque, al-Haram.
Every year, approximately 200 million pilgrims attend the Hajj, the fifth pillar of Islam, and an obligation that must be carried out at least once in their lifetime by every Muslim who can afford to do so.
The task of designing this structure was assigned to Christopher Wren in 1668, along with over 50 other City churches. His first design, to build a replacement on the foundations of the old cathedral, was rejected in 1669.
