During the Netherlands' "Golden Century" -- the 1600s -- Hoorn was an important harbor town in North Holland. It is on the IJsselmeer, a large body of water previously known as the Zuiderzee until the 1930s, when a new dam was built to separate it from the North Sea.
The headquarters of the Dutch East India Company were in Hoorn. Sailors rounding the bottom of South America named it Cape Horn after the town from which they had departed.
It was very cold here, too.
