Karnak Temple Complex is an archaeological site in Egypt. The site comprises a vast mix of decayed temples, chapels, pylons, and other buildings. Building at the complex began during the reign of Senusret I in the Middle Kingdom and continued into the Ptolemaic period, although most of the extant buildings date from the New Kingdom. Karnak was inscribed as a UNESCO World Heritage Site in 1979 as part of Ancient Thebes with its Necropolis.
