Around the corner and two streets away from St. Stephen's Cathedral are the partially excavated ruins of Vindobona, the ancient Roman fortress that gave Vienna its name.
Some of the ancient layout has been marked in red stone on the streets above, although the fortress itself was completely buried after the fall of the Roman Empire and only rediscovered in recent centuries. An underground exhibit displays actual walls and baths that were built by the Romans, built over by the Viennese, and subsequently unearthed for their historic interest. Also on display are ancient Roman artifacts that were found in the ruins.
