The temple complex of Karnak is located on the banks of the River Nile some 2.5 kilometers (1.5 mi) north of Luxor. It consists of four main parts, the Precinct of Amon-Re, the Precinct of Montu, the Precinct of Mut and the Temple of Amenhotep IV (dismantled), as well as a few smaller temples and sanctuaries located outside the enclosing walls of the four main parts, and several avenues of ram-headed sphinxes connecting the Precinct of Mut, the Precinct of Amon-Re and Luxor Temple.
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 work began in the 16th century BC. Approximately 30 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 is overwhelming.
