Hoorn's Waag is the 1609 weighing house on Rode Steen, the city's central square. Its facade, with a unicorn from the city crest, recalls the market trade that helped make Hoorn prosperous in the Dutch Golden Age.
It is a quick stop, best seen while exploring Rode Steen and the nearby Westfries Museum. The building also gives context to Hoorn's cheese-market history and the square's role as the old civic heart of town.
