A dome tops this neoclassical arch, which was built in 1770 as a gateway to the city. On the south side you'll see the Amsterdam emblem of three St Andreas' crosses, while on the other side there's a cog ship emblem, which appeared on Amsterdam's coat of arms in medieval times.
In 1811 Napoleon rode triumphantly through the gate with his royal entourage, and promptly demanded food for his ragged troops.
