The centre of Bruges is egg-shaped, defined by a loop in a river that was turned into a watery and defendable full circle by a canal and wall. Its security, and closeness to England across the Channel, made it one of the biggest trading hubs of Europe from the 12th to the 15th centuries. Italians with products from the Mediterranean, Portuguese with Indian pepper and spices, French with grains and wines and English with wool, all traded here.
The Bruges Bourse, the world's first stock exchange, opened in 1390 and a sophisticated money market developed offering banking, money changing and maritime insurance. Manufacturing also evolved, especially spinning and weaving, making Flemish cloth famous.
By the late 1400s, Bruges had a population of 200,000 and was known for its extravagant architecture and luxurious living. Then the river silted-up and the action was over. Antwerp became the hub of the Low Countries and Bruges quietly withered away.
It wasn't important enough for either the allies or the Germans to waste bombs on. But, after the war, when many heritage cities had been destroyed, Bruges, with its plethora of medieval and gothic buildings, became popular. Hundreds of buildings that had seen better days were snapped up and restored. Art, culture, festivals and fine dining flourished and still does today.
