Künzing sits on the Danube in Lower Bavaria, in a broad, fertile plain known as the Gäuboden, and in Roman times it was a place with a name, Quintana. The Romans built a fort here in the second century, one of the posts on the river frontier of the province of Raetia, and a civilian settlement, a vicus, grew up beside it, with houses, workshops and even an amphitheatre. The Danube Limes in Germany, Austria and Slovakia was listed by UNESCO in 2021, and Künzing is one of the places where it is easiest to grasp what daily life along the frontier was like.
The fort itself lies under fields and the modern village, but the museum, built over excavated Roman buildings, shows what was found, including pottery and everyday tools. The most unusual part is that the museum is built over the dig, so you can see the foundations of Roman buildings exactly as they were uncovered. The amphitheatre, which held a few thousand spectators, is a grassy bowl, and gives an idea of how the soldiers and their families spent their free time.
The surrounding region is gentle and green, with fields of maize and sugar beet, and wooded hills rising to the north into the Bavarian Forest. The Danube road is easy but not exciting, and a better ride goes up into the hills, where narrow roads wind through spruce woods and villages with onion-domed churches, and where in autumn the colours are spectacular. At Osterhofen, a few kilometres away, the Asam Basilica is a masterpiece of Bavarian rococo, designed by the brothers Cosmas Damian and Egid Quirin Asam in the 1720s, with gilded plaster, frescoes and a theatrical interior that comes as a surprise in a village church.
Passau, about twenty kilometres upstream, where three rivers meet, is a good place for a lunch stop, and the old town is a delight. Fuel, bakeries and cafes are found in Osterhofen and Künzing, and the local beer is excellent. A Bavarian lunch of pork roast with dumplings, followed by a coffee and cake, is a fine way to recover. The museum is open in the season and closes in winter, so check the dates.
