At the eastern terminus of Langestraat (Long Street) is Kamperbinnenpoort. The city gate was built during the 13th century as part of the first fortification of Amersfoort. The original name was Viepoort. Although Kamperbinnenpoort qualifies as the oldest gate, the most famous is Koppelpoort. The elaborate water and land gate was built in 1425 during the second fortification.
