In 1959, various supply lines to the well system were discovered, from which the population of the former Niederemmel (now Piesport) drew their daily water requirements and led their cattle to the drinking trough for centuries.
One of these supply pipes was lined with a 14 cm thick screed, a mixture of lime and pebbles of Roman origin, at the level of the foundation. The 55 cm thick walls of the water tunnel were built with a light-colored, solid lime mortar and were still 1.20 m high. The well was therefore probably already used as a water source in Roman times. Later, the bailiffs of Hunolstein built their farmsteads and manor houses near the "Roman well".
Legend:
Roman experts had just completed the underground tunnels of a water pipeline in the former Roman country settlement of "Ambiliacum"
(Niederemmel) when the soldiers were ordered to march to Muguntiacum (Mainz). Their commander Servandus had his soldiers assemble at the Roman fountain and prepared to march.
Once they had invoked the protection of their local god "Mercurius Bigontius", horse and rider set off on the nearby "viaromana" (Roman road) with all kinds of war equipment. That's when it happened.
Servandus died of a sudden heart attack. It happened on the spot where Emperor Caracalla had a milestone erected in 213 AD. The soldiers buried their commander not far from the army road because they had to hurry. They carried earth in their shirts and piled a mound of earth over his body, which is still called the "Roman Tomb" today.
