Mecca houses the Masjid al-Haram, the largest mosque in the world. Saudi Arabia

Mecca houses the Masjid al-Haram, the largest mosque in the world. The mosque surrounds the Kaaba, which Muslims turn towards while offering daily prayer. This mosque is also commonly known as the Haram or Grand Mosque.

As the birthplace of Muhammad and the site of Muhammad’s first revelation of the Quran (specifically, a cave 3 km (2 mi) from Mecca), Mecca is regarded as the holiest city in the religion of Islam and a pilgrimage to it known as the Hajj is obligatory for all able Muslims. Mecca is home to the Kaaba, by majority description Islam’s holiest site, as well as being the direction of Muslim prayer. Mecca was long ruled by Muhammad’s descendants, the sharifs, acting either as independent rulers or as vassals to larger polities. It was conquered by Ibn Saud in 1925. In its modern period, Mecca has seen tremendous expansion in size and infrastructure, home to structures such as the Abraj Al Bait, also known as the Makkah Royal Clock Tower Hotel, the world’s fourth tallest building and the building with the third largest amount of floor area.
