Answer
Mecca or Makkah is the holiest place for the Muslims. It is mentioned in the Koran as "Al Balad Al Amin", the Holy Land, The Sacred Land. It has the House of Allah (the cuboid structure called Kaaba), built first of all by Abraham and his son, and subsequently repaired by Prophet Mohammad (peace be upon him) and others.
The Muslims pray 5 times a day in the direction of the Kaaba.
They perform the small pilgrimage or Umrah (7 times around Kaaba and 7 rounds between Mounts Safa & Marwah)
They perform the Hajj (Umrah plus more rituals) during the time of Hajj.
It iforbidden to do any evil in makkah, since it is a holy land. Every good deed (or prayer) is worth 100,000 rewards in Makkah.
