The viaduct was constructed in just 20 months using approximately 30,000 cubic meters of stone.
During World War II, the bridge was heavily damaged by aerial bombardment in 1944 and subsequently rebuilt by 1949.
The structure is an integral part of the 'Viadukt Wanderweg', a 30-kilometer-long hiking circuit.
The bridge was built as part of the Westphalian Railway project to connect the Ruhr area with the Weser region.
It is listed as a technical monument due to its pioneering engineering significance in mid-19th-century railway construction.
The Altenbeken Viaduct is the longest stone railway bridge in Europe, stretching 482 meters across the Beke Valley. Completed in 1853, the structure utilizes 24 arches built primarily from local limestone. It remains a functional, active railway bridge on the Hamm-Warburg line, facilitating daily passenger and freight traffic. The viaduct stands 35 meters high, significantly shortening the distance between Paderborn and Warburg. Visitors can access a dedicated panoramic path that runs beneath and alongside the structure for architectural observation. The monument serves as a central symbol of the railway history in the Paderborn region.
The designated viewing platform on the hillside offers a head-on perspective of the entire arch span.
Walk the designated 'Viadukt Wanderweg' loop for varied perspectives of the arches from both the valley floor and the hillside.
Bring binoculars if you are a train enthusiast, as the bridge is a frequent transit point for diverse rolling stock.
Wear sturdy hiking boots, as the paths around the valley slopes can be steep and uneven.
Attempting to climb onto the bridge structure or walking along the active rail tracks.
Maintain distance from the active railway tracks; unauthorized access to the bridge deck is strictly prohibited and dangerous.
