Iron Age Architectural Complex Discovered in Aschaffenburg
In March 2026, construction workers in Aschaffenburg, Germany, stumbled upon an Iron Age architectural complex while digging a water retention basin at a depth of 8 meters. Dendrochronological analysis of oak samples, conducted by experts, revealed they date back to the 4th century BCE, making the find approximately 2,400 years old. The structure ended in a dry stone wall facing the Main River—a rare feature for this region. This discovery points to the existence of a sophisticated settlement from the La Tène period.
The find was made entirely by chance during routine building work. Authorities notified the Bavarian State Office for Monument Protection about the archaeological site. Previously, this area was not considered an archaeological zone, but the discovery has opened up new research opportunities. Dr. Stefanie Berg, head of the archaeological monument preservation department, noted that further studies are needed to determine whether the structure was part of a riverside port, a fortification, or a large public building.
Significance of the New Discovery
Earlier finds in Aschaffenburg's old town district had yielded individual La Tène artifacts, including gold and a fibula featuring an animal head design. However, this new discovery, buried between 8 and 10 meters deep, marks a major contribution to understanding the region's history. Experts emphasize that the dry stone wall uncovered during the excavation is exceptionally rare for the Iron Age in this part of Germany.
The object was accidentally encountered during construction of the water retention basin, according to the Bavarian State Office for Monument Protection. Ongoing research may provide more insight into the purpose and significance of this architectural structure within the La Tène period context.
This find has the potential to significantly reshape our understanding of Iron Age development in the region. It opens up new avenues for archaeological investigation that could shed light on the social and economic organization of settlements from that era. Given the importance of such discoveries, experts hope that further excavations will yield fresh data on the cultural and technological achievements of the La Tène period. This could deepen our knowledge not only of Aschaffenburg’s history but also of the broader territory of modern-day Germany.
