Medina, is a city in western Saudi Arabia. It lies on a fertile plain about 270 miles north of Mecca. Medina and Mecca are the holiest cities in Islam, the Muslim Religion, and only Muslims may enter there.
The Holy Mosque of the Prophet Muhammad, who founded the religion known as Islam, is in Medina. This Muslim house of worship holds Muhammad's tomb. Islam requires every Muslim to make at least one pilgrimage to Mecca if he or she can do so. Most pilgrims who visit Mecca also go to Medina.
