Roman ruins discovered at former Óbuda Soda Factory site

Archaeologists have discovered significant Roman-era ruins during the construction of the Waterfront City residential complex on the site of the former Óbuda Soda Factory in Budapest. The find is considered highly unusual for Hungary, where most Roman remains are only knee-deep; however, these walls stand at human height.

The structure includes a 55-meter long and 8-meter wide corridor, along with a 15-meter section that archaeologists are currently referring to as a “tower.” The ruins feature well-preserved Roman stucco on the exterior and smooth, white-limed plaster on the interior. Researchers have identified two floor levels: an upper layer of rolled clay with stone steps, and a lower terrazzo floor believed to be the original walking surface.

While the exact function of the building remains unknown, experts suggest it may have served as a fortification or been part of a larger complex. This discovery follows previous finds in the area, such as a 3rd-century Mithras temple and various cult objects. The heritage protection authority will ultimately decide the fate of the ruins, which currently sit within a major urban development zone.
