In 687-691, during the Second Fitna, the Dome of the Rock was built under Caliph Abd al-Malik ibn Marwan, becoming the world's first great work of Islamic architecture. The Temple Mount (known as Haram Ash-Sharif in the Islamic world and the site where the Islamic prophet Muhammad is believed by Muslims to have begun his nocturnal journey to heaven), had remained unbuilt for c. 600 years since Titus's destruction of Herod's Temple in 70.
