A bit of a thirst for adventure is important: you can visit the channel of a Roman aqueduct not far from a villa near Pölich. The channel is 1.20 m high and half a metre wide, and is openly accessible. It was carved out of the slate hillside and apparently supplied the baths of a large Roman villa. Such luxury was not uncommon then, and bears testimony not just to the remarkable technical skills of the Romans but also to their enormous water consumption. There is a small information centre about the aqueduct in the neighbouring old fire station.
