Tobruk

Also spelled  Tubruq  port, northeastern Libya. It was the site of Antipyrgos, an ancient Greek agricultural colony, and thereafter of a Roman fortress guarding the Cyrenaican frontier. The town later became a way station on the coastal caravan route. Because it is Libya's only natural harbour, Tobruk was occupied by the Italians as early as 1911 and was subsequently used as a naval and air base
