“ The town derives its importance from being the port of Constantine. The harbour works, with every vessel in port, having been destroyed by a storm in 1878, a more commodious harbour was built, at a cost of about £1,200,000. From Cape Skikda, on the east a mole or breakwater projects 4592 ft. to the W.N.W., while from Château Vert on the west another mole runs out 1312 ft. to the north, leaving an entrance to the port about 656 ft. wide. The protected area comprises an outer and an inner basin. The depth of water at the entrance is about 33 ft., alongside the quays about 20 ft. ”
