About Constantine

Constantine is built on a rocky plateau cut by the Rhumel gorge, so the city hangs over the river and its two halves meet on a series of high bridges. The Sidi M'Cid suspension bridge is the best known, with the Palace of Ahmed Bey and the museum of Cirta close by in the old town. The Roman ruins of Tiddis lie within a day's reach, and the coast is an hour or so north. Spring and autumn suit walking the bridges and streets; summer is hot and winter is wet and cool.
