This gem on the Graslei in Brabantine Gothic style was for centuries the home of the Guild of the Vrije Schippers. On the first floor, you can admire the motto of Keizer Karel, "Plus oultre", and the coat of arms of his empire. Since 1943, it has been a protected monument. North Sea Port bought the building in 2011, restored it and opened it to visitors: the harbor thus returned to its birthplace. Visit the exhibition about the operation of the harbor.
