A flash of white every four seconds. That’s the rhythmic pulse of the Unterfeuer Lemwerder guiding ships along the Weser. This unassuming structure plays a vital role in maritime safety. It marks the Fahrwasser or waterway between Berne and Lemwerder.
The Unterfeuer Lemwerder is part of a pair. It works in tandem with its taller sibling the Oberfeuer. Together they form the Richtfeuerlinie Lemwerder. This is the southernmost directional light on the Unterweser.
These lights are not just pretty beacons. They are essential aids to navigation. They help vessels stay on course. They ensure safe passage along this busy waterway.
The Unterfeuer Lemwerder itself is a relatively modern creation. It was put into operation in April 1983. It replaced an older system. The tower is a red steel tube. It features a white band and a red lantern. A balcony and pointed dome top it off. It stands sixteen meters tall. Its light shines from fifteen meters above sea level.
Its partner the Oberfeuer is 430 meters inland. It stands behind the dike. This tower is 27 meters tall. Both lights emit a synchronous white light. This light has a four-second cycle. The range of the Unterfeuer is about 15 nautical miles.
Before these modern structures, older beacons guided sailors. The first lights were established in 1898. This was during the Weser correction project. The old Oberfeuer was built by Bremer Vulkan. It served faithfully until 1983.
That original Oberfeuer still stands. The community of Lemwerder saved it in 1986. It was fully renovated in 1992. Today it is known as the Schwarzer Leuchtturm. This translates to Black Lighthouse. It is a local landmark. Unfortunately visitors cannot climb inside. There was also an Unterfeuer. It stood 640 meters away. This older structure was eventually torn down.
The Unterfeuer Lemwerder is more than just a light. It is a symbol of Lemwerder’s maritime history. It is a testament to the town’s connection to the Weser River. It stands as a practical aid. It ensures safe passage for ships. It connects Lemwerder to the wider world. So next time you see its flash, remember the history. Remember the purpose of this steadfast guide. It keeps watch over the waters of the Weser.
