Semaphore in Cuxhaven

The Semaphore in Cuxhaven is a tall signal building with wooden and metal moving arms positioned at the harbor. The structure consists of a sturdy tower on which the arms could be moved to different positions to send coded messages to passing ships.

The building was constructed in 1883 to warn ships approaching Cuxhaven harbor and convey information to them. It was one of the region's most important communication methods before radio technology transformed shipping.

The structure takes its name from the mechanical arms that resembled flags used in signaling. Visitors can see how it stands by the harbor and reflects the way ships once received important messages before radio existed.

The semaphore sits directly by Cuxhaven harbor and is easily reached on foot from the town center. Visitors should plan for good weather, as the structure stands in the open and is viewed from the outside.

The semaphore could make messages visible over kilometers by having each arm position represent a different letter or number. Sailors learned these codes to understand weather warnings and harbor news without needing to get closer.
