Tens of thousands of people move around the Kaaba inside the Grand Mosque during Hajj.
Hajj, the largest pilgrimage in the world, will be broadcast live on YouTube for the first time.
About 2.5 million Muslims are expected to travel to Mecca, Saudi Arabia, for the annual Islamic ritual on Nov. 5. Mecca's Grand Mosque houses the Kaaba, which is considered Islam's holiest site. Thousands of muslim pilgrims will move around the holy Black Stone in the center of the mosque.
"The Hajj represents one of the five pillars of Islam," Google wrote on its blog. "It requires all Muslims around the world who are able-bodied and can afford it to perform the pilgrimage once in their lifetime."
You can watch the live stream on the Saudi Ministry of Culture and Information's YouTube channel: http://www.youtube.com/hajjlive. It is also embedded below:
