Overview
The complex is a vast open-air museum and the largest ancient religious site in the world. It is believed to be the second most visited historical site in Egypt; second only to the Giza Pyramids near Cairo. It consists of four main parts of which only the largest is currently open to the general public. The term Karnak often is understood as being the Precinct of Amun-Re only, because this is the only part most visitors normally see. The three other parts, the Precinct of Mut, the Precinct of Montu, and the dismantled Temple of Amenhotep IV, are closed to the public. There also are a few smaller temples and sanctuaries located outside the enclosing walls of the four main parts, as well as several avenues of goddesses and ram-headed sphinxes connecting the Precinct of Mut, the Precinct of Amun-Re, and the Luxor Temple.
The Precinct of Mut is very ancient, being dedicated to an Earth and creation deity, but not yet restored. The original temple was destroyed and partially restored by Hatsheput, although another pharaoh built around it in order to change the focus or orientation of the sacred area. Many portions of it may have been carried away for use in other buildings.
The key difference between Karnak and most of the other temples and sites in Egypt is the length of time over which it was developed and used. Construction of temples started in the Middle Kingdom and continued through to Ptolemaic times. Approximately thirty pharaohs contributed to the buildings, enabling it to reach a size, complexity, and diversity not seen elsewhere. Few of the individual features of Karnak are unique, but the size and number of features are overwhelming. The deities represented range from some of the earliest worshiped to those worshiped much later in the history of the Ancient Egyptian culture. Although destroyed, it also contained an early temple built by Amenhotep IV (Akhenaten), the pharaoh who later would celebrate a near monotheistic religion he established that prompted him to move his court and religious center away from Thebes. It also contains evidence of adaptations, using buildings of the Ancient Egyptians by later cultures for their own religious purposes.
One famous aspect of Karnak, is the Hypostyle Hall in the Precinct of Amun-Re, a hall area of 50,000 sq ft (5,000 m2) with 134 massive columns arranged in 16 rows. 122 of these columns are 10 meters tall, and the other 12 are 21 meters tall with a diameter of over three meters.
The architraves on top of these columns are estimated to weigh 70 tons. These architraves may have been lifted to these heights using levers. This would be an extremely time-consuming process and also would require great balance to get to such great heights. A common alternative theory about how they were moved is that there were large ramps made of sand mud brick or stone and the stones were towed up the ramps. If they used stone for the ramps they would have been able to build the ramps with much less material. The top of the ramps presumably would have either wooden tracks or cobblestones for towing the megaliths.
There is an unfinished pillar in an out of the way location that indicated how it would have been finished. Final carving was executed after the drums were put in place so that it was not damaged while being placed. Several experiments moving megaliths with ancient technology were made at other locations – some of them are listed here.
In 2009 UCLA launched a website dedicated to virtual reality digital reconstructions of the Karnak complex and other resources.
