Mecca is the spiritual heart of Islam, because the Prophet Mohammed received his first revelations there in the early seventh century. According to the Quran, the cube-shaped Kaaba was built by Abraham and his son Ishmael. Kaaba’s doors have piqued the imagination of monarchs and rulers throughout Mecca’s history since Abraham erected it and called for Hajj 5,000 years ago. According to historians, the Kaaba originally had no door or roof and was just formed of walls. A series of images shot of the Kaaba in Mecca, about 1887, of Mecca and its environs. During the Hajj, pilgrims surround the Kaaba in Mecca, Saudi Arabia.
