Thyborøn — Skagerrak Codes

Your quest for the Skagerrak codes begins at Thyborøn Fyr, the coastal lighthouse built in 1878 at the entrance to Thyborøn harbor. This 12-meter high white masonry structure, with its red lantern, is a historic maritime landmark. It guided navigation in the Skagerrak Strait, a strategic area for 20th-century naval campaigns. This lighthouse, still active and listed in the Danish coastal monuments register, holds the first clues in a series of messages to decipher, linked to naval operations from 1940-1945.

Continue your investigation at Thyborøn Havn, the fishing port established in the 19th century, which became one of the most important in Western Jutland. Its infrastructures were strategic during World War II, with the Skagerrak passage mentioned in Allied operations. The port district retains period buildings, such as warehouses and fish markets dating from the early 20th century. These places, which now host hundreds of commercial fishing boats, will reveal information about ship movements and smuggling activities.

Walk along the Thyborøn Dige, the coastal protection dike built to prevent erosion and flooding, characteristic of the Jutland coast. This promenade, which offers direct observation of the Skagerrak and port activities, was a strategic historical maritime surveillance point. Crucial information about patrols and coastal defenses was exchanged here. It is here that light signals and radio messages passed through, allowing you to reconstruct part of the secret communications.

Your journey then takes you to the Kystcentret Thyborøn, the maritime and ecological interpretation center. This place documents the coastal history of the Skagerrak and marine life, with exhibitions on local ecosystems, notably mentioned in ASCOBANS studies on North Sea cetaceans. Although more recent, the center houses archives and old maps that will help you contextualize naval operations and understand the environmental and strategic importance of the Thyborøn region.

Finally, your investigation concludes at Thyborøn Kirke, the church built in 1904 in typical Danish Neo-Gothic architecture, and the Mindesten for omkomne fiskere, the memorial to lost fishermen. The church, dedicated to the fishing community, contains commemorative stained-glass windows. The memorial, erected in the 20th century near the port, is an annual place of remembrance that reflects the human cost of the coastal fishing industry. These sites, landmarks of Thyborøn city center, will allow you to decipher the final message, a tribute to the sacrifices of the sea and the resilience of Jutland.
