The gate was built as part of the city's second defensive wall, which was completed between 1380 and 1450.
It is a 'land and water gate' hybrid, allowing both road traffic and canal boats to pass through under different defensive mechanisms.
The water gate section features a massive wooden portcullis that could be lowered into the river to prevent boat access.
The interior contains a treadmill-powered hoist system, historically used by prisoners to operate the heavy gates.
The Koppelpoort is the only remaining water gate in the Netherlands that still retains its original defensive structure.
The building suffered damage during various conflicts but underwent extensive restorations in the 19th and 20th centuries to preserve its medieval integrity.
The Koppelpoort is a unique 15th-century combined land and water gate forming part of the second defensive wall of Amersfoort. It consists of a gatehouse for road traffic and a water gate that straddles the Eem river. The structure features a portcullis mechanism and defensive towers that were essential for the city's fortification system. Built around 1400, it remains one of the few surviving gates of its kind in the Netherlands. The gate is constructed from brick and limestone, showcasing medieval military architecture. It serves as a prominent landmark at the edge of the historic city center. Visitors can observe the heavy chains used to lower the water gate during times of conflict.
