Federseemuseum Bad Buchau, Natural history museum in Bad Buchau, Germany.

Federseemuseum is a natural history and archaeology museum in Bad Buchau that displays original finds from the wetlands around the Federsee lake. The outdoor area features reconstructed houses from the Stone Age and Bronze Age, showing how people actually built and lived in those periods.

The Federseemuseum was founded in 1919 by the Verein für Altertumskunde und Heimatpflege and first housed in the castle at Bad Buchau. Its collection grew through the work of the University of Tübingen's prehistory seminar; during the Second World War the holdings were moved out, then shown provisionally in the Reichsstift Buchau. The new building was occupied in 1968, and in 2003 the museum passed to the Archäologisches Landesmuseum Baden-Württemberg.

The museum displays stone and bronze tools, weapons, and everyday objects left behind by communities who lived by the lake. Walking through the reconstructed houses gives a concrete sense of how closely life was tied to the water.

The museum sits at the edge of Bad Buchau and is easy to find, with parking close by. The outdoor area with reconstructed houses requires some walking, so comfortable shoes are a good idea.

The archaeological sites around the museum are part of a UNESCO World Heritage group covering prehistoric pile dwellings around the Alps. What makes them especially valuable is that organic materials like wood and textiles have survived in the waterlogged soil in a way that is rare on dry land.
