The Masjid al-Haram is the most holiest and prestigious mosque. It is also the largest mosque of the world and had gone through many enlargements and changes throughout the history due to the increasing number of pilgrims. The Ka’bah which is the holiest building of Islam is at the focal point of Masjid al-Haram.

Islamic architecture began in the Grand Mosque in Makkah Al-Mukarramah since the era of the Rightly Guided Caliphate, as the first increase in the construction of the Grand Mosque came during the days of the Commander of the Faithful Omar bin Al-Khattab, may God be pleased with him, the impact of a great torrent that raided Mecca in the year 17 AH. And he made a wall for the mosque whose height was less than stature, and lamps were placed on it, so Umar ibn al-Khattab was the first to surround the mosque with a wall, and he was the first to expand it, so he made doors for it.
