Berenice or Berenice Troglodytica, also known as Baranis, is an ancient seaport of Egypt on the west coast of the Red Sea. It is situated about 825 km south of Suez and 260 km east of Aswan in Upper Egypt.It was founded in 275 BC by Ptolemy II Philadelphus, who named it after his mother, Berenice I of Egypt. Troglodytica refers to the aboriginal people of the region, the "Troglodytai" or "cave dwellers". Although the name is attested by several ancient writers, the more ancient Ptolemaic inscriptions read Trogodytai. It is possible that later copyists confused this name with the more common term Troglodytai.
Built at the head of a gulf, the Sinus Immundus, or Foul Bay, of Strabo, it was sheltered on the north by Ras Benas. A lofty range of mountains runs along this side of the African coast, and separates Berenice from the Nile Valley.
