Ballum Sluse

Ballum Sluse directs water from Brede Å River through the Ballum-Alstrup dike, managing the flow between inland waterways and the Wadden Sea.

The construction of this red brick lock began in 1914, with French and Russian prisoners of war completing most of the work during World War I.

The lock represents an essential component of Danish water management infrastructure, demonstrating the relationship between local communities and coastal environments.

Visitors can access viewing points along the dike path to observe the lock mechanisms and water management system throughout the year.

The lock creates specific conditions where millions of starlings gather during spring and autumn migrations, performing synchronized flight patterns near sunset.
