Mark Twain (American author): "Benares is older than history, older than tradition, older even than legend, and looks twice as old as all of them put together."

19. Cádiz, Spain

When did the earliest inhabitants settle? 1,100 BC

Found on a narrow spit of land jutting out into the Atlantic Ocean, Cádiz has been the home of the Spanish navy since the 18th century. It was founded by the Phoenicians as a small trading post and fell to the Carthaginians around 500BC, becoming a base for Hannibal's conquest of Iberia. It then came under Roman and Moorish rule, before experiencing a renaissance during the Age of Exploration.

Robert Browning, the English poet and playwright, wrote: "Nobly, nobly Cape Saint Vincent to the North-west died away/ Sunset ran, one glorious blood-red, reeking into Cádiz bay."

It became an important settlement after the arrival of the Aramaeans, who established a network of canals, which still form the basis of its modern water networks. Another of Alexander the Great's conquests, Damascus has since been in Roman, Arab and Ottoman possession. Its wealth of historical attractions made it a popular tourist destination, until recent unrest struck.

Hilaire Belloc (English-French writer and historian): "Damascus is... a symbol. One might call it a bunch of symbols. It is a symbol of the permanent physical conditions that run throughout history; the permanent geographical limits of human settlement, government and war."

3. Aleppo, Syria

When did the earliest inhabitants settle? 4,300 BC

Syria's most populated city with around 4.4 million citizens Aleppo was founded as Halab in around 4,300 BC. As the ancient site is occupied by the modern city it is barely touched by archaeologists.

It was later occupied by the Romans, Byzantines and Arabs, besieged by the Crusaders and then taken by the Mongols and Ottomans.
