Месса, also transliterated Makkah, is a city in the Hejaz in Saudi Arabia. It is the capital of that kingdom's Makkah Region.

Mecca - the holy city of Muslims. In the year 630, reinforcing its position as the Muslim community of Medina, led by the Prophet Muhammad entered Mecca, the city surrendered without a fight, the people embraced Islam. Mecca with the holy Kaaba was transformed into a religious center, and Muslims began to pray facing Mecca, wherever they are.
"Mecca" is the familiar form of the English transliteration for the Arabic name of the city, although the official transliteration used by the Saudi government is Makkah, which is closer to the Arabic pronunciation.The word "Mecca" in English has come to be used to refer to any place that draws large numbers of people, and because of this many Muslims regard the use of this spelling for the city as offensive.
