Seeteufel writes: Mecca is the holy site of Islam. The center of worshipping is a black stone (Al-ajaru l-Aswad) in a corner of the Kabah complex. Saudi Arabian pilgrimage industry lead to ongoing radical rebuilding and a destruction of the ancient sites in the holy city. This summer the Bin Laden group finished a giant skyscraper complex next to the Mosque, a 485-metre-high Mecca clock tower, the alleged birth place of Muhammed was destroyed. According to the Saudi teachings preserving ancient sites would be idolatry. Ambitious plans for Mecca 2020 comprise a strange architectural mix between the World Trade Center, Speer's Germania plans and Las Vegas. Do you think cultural heritage should be preserved?
