History of urban centres in the Low Countries
The development of urban centres in the Low Countries shows the process by which the Low Countries, a region in Western Europe, evolved from a highly rural outpost of the Roman Empire into the largest urbanised area north of the Alps by the 15th century CE. As such, this article covers the development of Dutch and Flemish cities beginning at the end of the migration period till the end of the Dutch Golden Age. == Earliest settlements == The northern border of the Roman Empire, known as limes ad Germaniam inferiorem, was set at the Rhine in 47 AD. The border was protected with fortresses and the Low Countries became the outer provinces of the empire, situated near the Roman-Germanic border.
