Its recorded history starts with the Roman invasion halfway the first century A.D. but it had its heydays in the 17th century when it disputed hegemony of the Seven Seas with the English and the Spanish empires. In that period New York, parts of India, a series of forts along the African Coast and the Colonies in Indonesia formed part of the vast Dutch Empire.
Though most historic town centers in The Netherlands date back to the Dark Ages, most building was done in era of oversea expansion and in the nineteenth century when the country finally took the industrial revolution seriously. In Amsterdam, Leiden or Utrecht you can see the big 17th century mansions once owned by the commanders of the Dutch fleet and those of the rich merchants who financed the wars with their overseas gains. They were the Dutch elite by lack of real aristocracy. The preferred small items of great value stashed away in their mansions over baroque palaces. Though the Dutch never were really extravagant and did not have a real court like there were in Germany, France and Spain, they were very proud of themselves. This can still be seen in the countless portrait paintings they commissioned. They also were the patrons of the famous Dutch painters like Rembrandt, Van Hals or Vermeer.

Maastricht is the most important city of the South. The atmosphere is quite different from the North. The town is pretty and is a good base for exploring the countryside as well as making daytrips to Aachen and Liege.
Because of its size and flatness The Netherlands is a great country to explore by bicycle. Public transport is another good option because parking is problematic in most town centers. Trains and buses provide excellent transport in the entire country, though in the eastern part it sometimes pays off to rent a car.

The Dutch aren't bogged in their cliches, even though bikes, dykes, windmills and blazing flower fields are pretty much the norm outside the major cities. Do as the locals do - grab a bike and explore. It's a very big small country, and full of salutary surprises.
One of the chief pleasures of the place is its lively contrast between pragmatic liberalism and the buttoned-up just-so primness of a culture founded on Calvinist principles. In Dutch society, ostentation is anathema and fuss of any kind is regarded as undignified.
For travellers, the integration of the clog and the microchip works well. The Netherlands is easy to travel in and the locals are friendly and speak excellent English, but many towns are still surrounded by canals and castle walls, the endlessly flat landscape which inspired the nation's early artists still stretches unbroken to the horizons, and the dykes still occasionally threaten to give way.
