One of the most prominent landmarks of Mina is the Jamarat or the Jamrah Pillars that are thrown at the Jamarat Bridge. The three Jamarat are located in Mina Valley. Currently, they are within the Jamarat Bridge, which is one of the great achievements of the Kingdom’s Government, in order to organize crowds and provide safety when they go to throw Jamarat. At the beginning of the Day of Nahr, only the seven pebbles of the biggest Jamrah are thrown. During the days of Tashreeq, each Jamrah is thrown at with seven pebbles, from the Smallest Jamrah, the Middle Jamrah, and finally the Biggest Jamrah. A pilgrim can throw Jamarat from any floor of the Jamarat Bridge. It is very important for pilgrims to abide by the schedule of Tafweej (Group Dispatching) set by the organizers for throwing Jamarat and the directions of movement, in order to maintain the safety and security of others. The Jamarat Bridge is one of the pioneering projects that has made a civilizational and engineering leap in the service of pilgrims. The Jamarat Facility consists of four floors, in addition to the ground floor. It is 80 meters wide and has 12 entrances for Jamarat and 12 exits in the four directions, which reduces overcrowding. The Bridge is linked to the pilgrim camps.
