The Great Wall of China visible today largely dates from the Ming dynasty, as they rebuilt much of the wall in stone and brick, often extending its line through challenging terrain. Some sections remain in relatively good condition or have been renovated, while others have been damaged or destroyed for ideological reasons, deconstructed for their building materials, or lost due to the ravages of time. For long an object of fascination for foreigners, the wall is now a revered national symbol and a popular tourist destination.
