In 1609 captain Henry Hudson, with his ship "De Halve Maen" (the half moon), sailed up the American river that received his name later on. Working as an explorer for the Dutch East India Company (VOC), he was searching a passage to the Orient.
Instead, he found fertile lands that were going to form the colony of New Netherland, with towns like Nieuw Amsterdam (New York), and Beverwijck (Albany).
The exibition that was on display at the Rijksmuseum in Amsterdam until June 1, with unique documents from the Dutch National Archives, will travel to New York. Starting September 13, 2009 at the South Street Seaport Museum.

Also in this region close to Amsterdam, with a couple of small fortified towns surrounded by a varied countryside and lots of water.
