A Windmill Tour of Schleswig-Holstein: Gallery Mills Between Two Seas
Stand on a dike anywhere in Schleswig-Holstein and you understand at once why this is windmill country. Germany's northernmost state is a low, open land squeezed between two seas, the North Sea on its western flank and the Baltic on its eastern shore, and the wind that sweeps across its marshes and gentle moraine hills rarely rests. For centuries that wind was harvested by hundreds of mills, and the type that came to define the region is the gallery smock mill, in German the Galerieholländer: a tall, usually octagonal tower wrapped at mid-height by a wooden gallery from which the miller worked. Many of these dignified giants still stand today, and following them from town to town makes one of the most rewarding themed journeys northern Germany has to offer.
The gallery smock mill, explained
A smock mill consists of a fixed tower, most often eight-sided and built of timber, carrying a rotating cap that holds the sails. Because only the cap turns, the tower itself can be built tall and roomy, with several working floors for grinding, sifting and storage. Height, however, creates a practical problem: the sails of a tall mill end far above the ground, out of the miller's reach. The gallery is the elegant answer. This wooden platform encircles the tower at the level where the sail tips pass closest, so the miller could step outside to spread or reef the sailcloth, tend the brake and keep an eye on the weather. In Schleswig-Holstein the tower typically rises from a brick base that held storage rooms and sometimes the miller's living quarters, while the smock above is clad in shingles or thatch against the driving rain. Most mills here also carry a fantail, the small wind wheel mounted behind the cap that turns the sails automatically into the wind, a refinement that spared the miller endless heavy work.
A Dutch idea takes root between the seas
The very name Holländer, used across Germany for this kind of mill, points to its origin. The smock mill was perfected in the Netherlands in the early modern period, and Dutch expertise travelled north-east along the coasts together with Dutch dike builders, drainage engineers and merchants. The marshlands of western Schleswig-Holstein, won from the sea behind long lines of dikes, were an environment the Dutch understood intimately, and their mill-building tradition found ideal conditions in a landscape with no mountains, no strong rivers and no shortage of wind. Over time the Dutch design displaced the older post mill, in which the entire body of the mill had to be turned on a central post. The smock mill was larger, more powerful and far more comfortable to work in, and by the nineteenth century it had become the standard windmill of the region. When the old milling monopolies were abolished in the course of that century and trade was freed, a wave of new mills went up, which is why so many surviving mills in Schleswig-Holstein date from the mid or late nineteenth century.
Amanda of Kappeln, a Baltic landmark
If the tour has a natural starting point, it is Kappeln, the little harbour town on the Schlei inlet in the region of Angeln. High above the water stands the mill Amanda, erected in 1888 and one of the best known windmills in the whole state. Amanda is a textbook gallery smock mill on a generous scale: a massive base, an octagonal shingled tower, a sweeping gallery and a cap crowned by a fantail. The mill long ago gave up grinding grain, but it has lost none of its standing in the town. Today it serves civic purposes and is a popular place to get married, with the registry office making use of the historic building, and it has appeared so often as a backdrop in German television productions filmed around Kappeln that many visitors feel they know it before they arrive. From the gallery there is a wide view over the Schlei, a reminder that mills were deliberately placed on exposed, elevated ground to catch every breath of wind.
Marsh, geest and island mills of the west coast
Cross the peninsula to the west and the landscape changes to the wide marshes of Nordfriesland, Eiderstedt and Dithmarschen, flat green land below the level of spring tides. Here windmills did double duty for generations: besides grinding grain, wind-driven scoop mills once helped lift water out of the drainage ditches and over the dikes, in the best Dutch manner. The grain mills of the marsh towns follow the familiar gallery pattern, their brick bases standing firm on the soft ground. Offshore, the North Frisian islands kept their mills too, since bringing grain to the mainland for grinding made little sense. The island of Föhr is particularly rewarding for mill lovers, with several preserved smock mills, among them the striking mill of Wrixum, a favourite subject for photographers. Amrum and Sylt also retain historic mills, and on the Baltic side the island of Fehmarn cares for its own milling heritage, with local associations keeping buildings and machinery in order.
What the mills do today
Hardly any mill in Schleswig-Holstein still earns its living by wind alone, but a surprising number have found second lives that keep their doors open. Some house museums of milling and rural life, with the gearing, millstones and sack hoists preserved in place. Others have become cafés, holiday homes, cultural venues or, as in Kappeln, wedding venues. A famous exception to the rule of retirement stands just outside Hamburg in Braak, where the Braaker Mühle, a gallery smock mill from the middle of the nineteenth century, remains the heart of a working bakery business and still sets its sails turning on suitable days. Preservation in the state rests largely on volunteers, and the regional mill association coordinates restoration knowledge, training and events. The best single date for a visit is Whit Monday, when the nationwide German Mill Day sees mills across Schleswig-Holstein open their doors, set their sails and demonstrate the old craft to anyone who climbs the stairs.
Planning the tour
A windmill tour of Schleswig-Holstein rewards slow travel. The distances are modest, the roads quiet, and the land so flat that a mill announces itself from kilometres away. A sensible route might begin on the Baltic side with Kappeln and the mills of Angeln and Schwansen, cross to the west coast through the marsh towns of Nordfriesland and Dithmarschen, and finish with a ferry to Föhr for the island mills. Cyclists are especially well served, since long-distance routes follow both coasts and pass within sight of many mills. Check opening arrangements before you travel, because many mills are run by volunteers and open only on certain days, and remember that a mill with turning sails deserves a respectful distance. Above all, take time to climb to the gallery where one is accessible: standing on those planks with the wind in your face is the closest a modern visitor comes to the working life of a nineteenth-century miller.
