Hollerkolonisation, Medieval land reclamation area in Stade and Hamburg, Germany
The Hollerkolonisation is a medieval land reclamation landscape in the region between Stade, Harburg, and Hamburg, where marshland was turned into farmland through drainage canals and dyke construction. Parallel waterways and dykes still divide the flat land into long, narrow plots today.
In the 12th century, the Archbishop of Bremen invited Dutch settlers to develop the marshy lowlands between Hamburg and Stade. This was part of a broader colonization movement that changed the coastal landscape of northern Germany.
The long, narrow fields and straight canals still follow a pattern that the settlers themselves designed. Communities managed the dykes and waterways together, and this shared responsibility shaped daily life in these villages for generations.
The area is best explored on foot or by bike, as dyke paths and field tracks give access to most of the canals and plots. Paths can get wet and muddy outside of summer, so sturdy footwear is a good idea.
The original land plots were measured using an old unit of length that settlers brought from the Netherlands, and many property boundaries still follow this pattern today. Walking along a dyke, you can read this geometric layout directly in the landscape below.
