Nyergesújfalu

Nyergesújfalu is a town in Komárom-Esztergom county, Hungary, in the Central Transdanubia region.

The city, located near the river Danube, is an ancient site of habitation. It was located on the Crumerum, a major Roman trade and military route. Late-era Romans built a fort here, to help protect the northern border of their empire. The settlement was later overrun by various tribes and, later still, by invaders from the Ottoman Empire. In the periods of warfare the fort was destroyed.

European travelers later noted the fort's ruins; for instance, in the mid-18th century, travel writer Richard Pococke wrote about it. "We saw the ruins of the fort, several Roman bricks and elsewhere foundations that seemed to be Roman." The struggle for freedom in the region in the later 18th century resulted in the destruction of most of the fort. A century later, not even remnant stones were visible.
