They were certain the lost Roman legionary fortress lay under the old town center of Neuss. Koenen, an amateur with no academic post, thought it was somewhere else - to the south, on open ground out by the confluence of the Erft with the Rhine. In 1886 he talked the Bonn Provincial Museum into letting him dig a test pit. The pit hit something. Over the next thirteen years Koenen and his team moved roughly fifty thousand cubic meters of soil, by shovel and wheelbarrow, and revealed the first complete ground plan of a Roman legionary fortress ever known anywhere in the world.

Novaesium: Buried Under Bungalows

Sat, 16 May 2026 00:00:00 GMT

Photo credit Hartmann Linge, Public domain. Here is the tragedy of Novaesium for modern archaeology: the city of Neuss built houses on top of it. Through the 1950s and into the 1980s, as the Gnadental district expanded south, rescue excavations raced ahead of construction crews, snatching what they could before the foundat...
