Bentumersiel

Bentumersiel is a former Roman fortification in the river marsh of the Reiderland on the lower Ems in Lower Saxony. The site lies in a flat, low-lying landscape where the Ems winds through wide grasslands. Evidence shows Roman legionnaires were present here at the start of the 1st century AD. The settlement was founded in the middle pre-Roman Iron Age and lasted until the 3rd or 4th century AD. Its buildings differ from typical Germanic marsh farms because they were not raised on artificial mounds. The site is important because it produced Roman objects alongside local pottery. Finds include metal parts of legionnaires’ equipment, shards of Roman amphorae and heavy ceramics. Many items date to the campaigns of Germanicus in 15/16 AD. Tacitus wrote that the Roman fleet stayed on the lower Ems during these operations. The mix of finds and the lack of permanent houses suggest Bentumersiel was used seasonally as a trading and supply post. Visitors find an open field where archaeologists have recovered Roman bricks and imported ceramics. Excavations in 1929, the 1970s and 2006 uncovered Germanic and Roman materials across at least 1.3 hectares. The site shows no clear northern boundary, so the settlement may have been larger. Nearby riverside places like Elsfleth-Hogenkamp provide comparison. The remains help explain how Romans used the Ems marshes during their early campaigns in Germania.
