The harbour lies on the eastern side of this promontory, but it is an unsafe roadstead, being unprotected towards the north-east and having been much silted up, so that vessels cannot approach within a considerable distance of the shore.
The Lukuga was reported blocked by a bar about 1897, but a certain amount of water was found flowing down by Mr Moore in 1899; while in 1901 Mr Codrington found the level 4 or 5 feet higher than in moo, the outlet having again silted up. A continued rise was also reported in 1907.
When the other branches and the Alexandria canal silted up, Rosetta prospered like its sister port of Damietta on the eastern branch; the main trade of the overland route to India passed through it until Mehemet Ali cut a new canal joining Alexandria to the Nile.
The ancient harbour (really but a portion of the lagoons, which had been deepened) is now completely silted up. Even in early times a canal had to be kept open by perpetual digging, while about 1700 this was closed, and now a sandy and partly cultivated waste extends between the town and the seashore.
But with the decline of Venice the trade of the port fell off; the mouth of the Lido entrance became gradually silted up owing to the joint action of the tide and the current, and for many years complete stagnation characterized the port.
The XXXII.-3 Euphrates and Tigris have within historical times silted up their mouths to an extent that has materially altered the coast-line of the Gulf and these rivers seem destined in the future to unite El Hasa to Fao, just as in the past they produced the fertile plains of Mesopotamia.
This in ancient times seems to have formed a group of islands intersected by arms of the Hypanis or Kuban and various sounds now silted up. The whole district was dotted with Greek cities; on the west side, Panticapaeum (Kerch, q.v.), the chief of all, often itself called Bosporus, and Nymphaeum (Eltegen); on the east Phanagoria (Sennaja),Cepi,Hermonassa,Portus Sindicus, Gorgippia (Anapa).
In the course of centuries this mole has been silted up and is now an isthmus half a mile wide.
But like other cities of Cyprus, it suffered repeatedly from earthquake, and in medieval times when its harbour became silted the population moved to Larnaca, on the open roadstead, farther south.
Its harbour was of some importance, but is now silted up, the sea having receded.
