Dried out section of Lake Mariout, used for salt refining
Lake Mariout (Arabic: بحيرة مريوط Boḥēret Maryūṭ , IPA: [boˈħeːɾet mɑɾˤˈjuːtˤ]; also spelled Maryut or Mariut) is a brackish lake in northern Egypt. The lake area covered 200 km² at the beginning of the 20th century, but at the beginning of the 21st century it covers only about 50 km². It is separated from the Mediterranean Sea by the narrow isthmus on which the city of Alexandria was built. The lake shore is home to fisheries and saltworks. Some of the marshy areas around the lake have been reclaimed for new building as the city grows.
The name derives from Mareotis or Marea, the name of the lake in ancient times.
