The famed Valley of the Kings, hidden between rocky escarpments, was the final resting place for the kings of the 18th, 19th, and 20th dynasties. Their main attraction is their wonderfully vivid wall paintings. Since it was believed that the dead man, accompanied by the sun god (or perhaps having become one with the sun god) sailed through the underworld at night in a boat, the walls of the tombs were adorned with texts and scenes depicting this voyage and giving the dead man instruction on its course. Within the valley are 63 tombs that are a roll-call of famous names of Egyptian history including the famous boy-king Tutankhamun. The tombs are open on a rotation system to preserve the paintings as much as possible from the damage caused by humidity.
