The lakeside city of Sabha is home to the striking bulwarks of Fortezza Margherita (now called just Fort Elena): one of the most dramatic and historic of citadels still standing in the country (it’s even depicted on the back of some Libyan banknotes!).
Above that, Sabha is also considered the best gateway to the Fezzan region, which rolls out to meet the Sahara Desert proper in a patchwork of date palm oases and undulating dunes from the southern edges of the town.
