Luxor Temple is a great temple complex dedicated to Amun, a creator god often fused with the sun-god Ra into Amun-Ra. Construction began during the reign of Amenhotep III in the 14th century BC and major expansion took place under Ramses II, about 100 years later, making Luxor unique among the main Egyptian temple complexes in having only two pharaohs leave their mark on its architectural structure. Its main purpose was to celebrate the festival of Opet. Each year, to ensure the flooding of the Nile that was necessary to national prosperity, the statues of Amun, Mut (goddess of war), and Khons (the moon god) were sailed down the river to Karnak for a great festival. Luxor Temple is vast , once housing a village within its walls. It has several pylons (monumental gateways). The first is over 70 feet high and flanked by massive statues and several obelisks. There are several open areas within the temple, once used for various forms of worship but now empty. The ceremonial entrance to the temple is from the north, where a causeway lined by sphinxes that once led all the way to Karnak begins. This road, known as the Sacred Way or Avenue of Sphinxes, was a later addition, dating from the time of Nectanebo I in the 30th Dynasty. The peristyle courtyard is followed by the processional colonnade built by Amenhotep III” a 100-metre corridor lined by 14 papyrus-capital columns. Friezes on the wall describe the stages in the Opet Festival, ordered by Tutankhamun. Through another peristyle courtyard are the the inner sanctums, which have Roman stuccos placed over Egyptian carvings. Further in stands a Barque Shrine for use by Amun, built by Alexander, with the final area being the private quarters of the gods and the Birth Shrine of Amenhotep III, which features detailed wall paintings depicting the pharoah’s claim to have been fathered by Amun, and therefore of divine descent.
