Mystery Bridge Nr. 85: A Covered Bridge with a Thatched Roof

IMGP7464

Thatching is a different but efficient concept for roofing a house. Houses with thatched roofs have a Roof that is built using dry vegetation, such as straw, sedge, heather, water reed, palm fronds and/or rushes and with that, each side of the house has a roof that slants downwards towards the outer edge. Thatched Roofs have a dual function where it allows water to flow off the outer roof, keeping the inner roof dry (and thus preventing rotting and molding of the wood), but at the same time, it acts as an insulator, keeping the warm air inside during the winter and outside during the summer months. Houses with thatches roofs can be found in Areas with tropical climates, but also those with a continental climate, such as the northern parts Germany, Belgium, the Netherlands, France and Great Britain.

While architects find creative ways to building houses with thatched roofs, it is also no surprise that one can find covered bridges with thatched roofs. One just has to stumble across something like this one, located just south of St. Peter-Ording in the German state of Schleswig-Holstein.

Located on a trail that separates the clinic and the Westküsten Park and Robbarium, this bridge Looks like a typical small crossing that spans a canal that transfers water from the North Sea to the fields to prevent flooding during high tides and severe storms but also to provide water to the farm lands nearby. The bridge is only seven to eight meters long, but the width is about 40 centimeters wider, especially if you count the overhead portion.  In bridge terminology, the bridge is a through truss using the Kingpost design. The entire structure is made of wood.

Yet looking at it further, it definitely has the thatched roof appearance, as two different layers are added to the roof to make it unusual. The top layer has either sedge or rush roofing, whereas the bottom layer has the typical reed roofing, one sees with houses in Schleswig-Holstein and neighboring Mecklenburg-Pommerania. This type of construction makes the bridge very unusual for a covered bridge, but it does lead to the question of whether this is the only bridge of ist kind in the region, Germany or even Europe, or if there are similar bridges of ist kind out there. and if so, where.

While the roof has the function of protecting the remaining elements from rotting or molding caused by moisture from rains, the structure itself is no older than 20 years old, for even though there is moss on some of the wooden beams, the bridge and its trusses look relatively new. Therefore, it is estimated that the bridge was built between 1995 and 2005, if not later. It is the question of who built it and why the engineer decided for this unique design.

If you know more about this bridge, please send the author an e-mail with some information about it. This will be useful for the upcoming book project on the bridges of Schleswig-Holstein. What is just as important (or even more) than this bridge is the following:

How many covered bridges have a thatched roof similar to this one? And where are they located?

 

A discussion Forum has been established on facebook, Twitter, LinkedIn and Instagram so that you can comment on this. Photos and info for the other bridges would be much appreciated.  🙂
