Luxor Temple is a large Ancient Egyptian temple complex located on the east bank of the Nile River in the city today known as Luxor and was constructed approximately 1400 BCE. In the Egyptian language it is known as ipet resyt, "the southern sanctuary" Luxor temple was built with sandstone from the Gebel el-Silsila area, which is located in South-Western Egypt. This sandstone from the Gebel el-Silsila region is referred to as Nubian Sandstone. This sandstone was used for the construction for monuments in Upper Egypt as well as in the course of past and current restoration works The Karnak Temple Complex, commonly known as Karnak from Arabic Khurnak meaning "fortified village"), comprises a vast mix of decayed temples, chapels, pylons, and other buildings near Luxor, in Egypt. Construction 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. The area around Karnak was the ancient Egyptian Ipet-isut ("The Most Selected of Places") and the main place of worship of the eighteenth dynasty Theban Triad with the god Amun as its head. It is part of the monumental city of Thebes. The Karnak complex gives its name to the nearby and partly surrounded, modern village of El-Karnak, and 2.5 kilometres (1.6 miles) north of Luxor.
