Schellfischtunnel, Railway tunnel in Altona, Germany
The Schellfischtunnel is a railway tunnel that runs roughly 1 kilometer beneath Altona's surface, once connecting the former station to the fishing harbor. The passage features brick lining and includes 21 safety niches where workers could shelter during train operations.
Construction took place between 1873 and 1895, replacing an earlier inclined system that suffered from repeated landslides. Service began with steam locomotives and switched to electric power in 1909, making this one of the region's early electrified rail lines.
The name comes from fish shipments that moved through here starting in 1889, reflecting Hamburg's role as a major distribution hub for fishing products in the region. Workers and transport companies relied on this passage as a key link between the city and the docks.
The tunnel is no longer in active railway service but can be visited through guided tours when available. The dark, damp underground environment means visitors should wear sturdy footwear and bring appropriate clothing.
Today the tunnel occasionally hosts art exhibitions and cultural events, offering an unusual underground venue for creative projects. This modern use shows how historic infrastructure has found a second life in Hamburg's cultural scene.
