or Ghudāmis
Oasis and town (pop., latest est.: 15,900), northwestern Libya.
Located near the Libyan-Algerian border, it is at the junction of ancient Saharan caravan routes. It was the Roman stronghold Cydamus (whose ruins remain), and an episcopal see under the Byzantine Empire; columns of a Christian church still remain in the Sīdī Badrī Mosque. A centre for the Arab slave trade through the 19th century, it is now a caravan depot linked to the Mediterranean Sea coast.
