"Mecca is the birthplace of Muhammad and the site of Muhammad's first revelation of the Quran . . . . and a pilgrimage to it is a requirement at least once for every Muslim." I learned about it on the Discovery Channel, and I think every Muslim also has to touch that center structure at least once. It receives 16 million visitors a year. For the pilgrimage, they walk in a rotation and move in and then out.
Fascinating.
But today a
crane collapsed during construction surrounding it. The result: 107 innocent people are dead.
