Prague's historic center is on UNIDO's list of World Heritage Sites.
 The World Heritage Sites list is maintained by the international World Heritage Program administered by the UNESCO World Heritage Committee, composed of 21 "states parties" that are elected by their General Assembly
 The Dresden Elbe Valley was first placed on the danger list in 2006 when the World Heritage Committee decided that plans to construct the Waldschlsschen Bridge would significantly alter the valley's landscape
