Berenice Troglodytica

Berenice Troglodytica, also called Berenike or Baranis, is an ancient seaport of Egypt on the western shore of the Red Sea. It is situated about 825 km south of Suez, 260 km east of Aswan in Upper Egypt and 140 km south of Marsa Alam.

It was founded in 275 BCE by Ptolemy II Philadelphus, who named it after his mother, Berenice I of Egypt.A high mountain range runs along the African coast and separates the Nile Valley from the Red Sea; Berenice was sited upon a narrow rim of shore between the mountains and the Red Sea, at the head of the Sinus Immundus, a south-facing bay sheltered on the north by a high peninsula then called Lepte Extrema, and to the south by a chain of small islands scattered across the mouth of the bay. One of them was called the Island of Ophiodes and was one of a few sources of gemstones local to Berenice. The harbour is marginal, but was improved by engineering.
