A short walk east of Leibnitz, the ruins of Flavia Solva are one of the most substantial Roman sites in Austria. The municipium dates to the first century AD, when it served as the administrative centre of this corner of the province of Noricum. The excavated remains include sections of the town plan, mosaic floors, and a lapidarium sheltering inscriptions and carved stone fragments.
The Museum Flavia Solva on the site presents finds from over a century of excavation, including everyday objects that give a sense of daily life in a prosperous Roman town. The mosaics are the highlight — their geometric patterns survive in remarkable condition. Allow a couple of hours to walk the site properly, especially in good weather when the views across the Sulm valley add to the appeal.
