Three exceptionally well-preserved mosaics, including a unique dolphin motif from the 2nd century AD, are turning the ongoing excavations in Thalheim bei Wels, Austria, into an archaeological sensation. Discussions are now underway regarding the future of the mosaics.

The discovery has been attracting attention for weeks: archaeologists from the OÖ Landes-Kultur GmbH and the University of Salzburg have uncovered a Roman building complex over 1,000 square meters in Thalheim bei Wels. The impressive estate on Reinberg – overlooking the ancient city of Ovilava (modern-day Wels) – is believed to have once belonged to a wealthy family. As for Olivava, it had been given the prestigious title of Colonia Aurelia Antoniana Ovilabis and was the capital of the Roman province of Noricum Ripensis.

Particularly spectacular are three Roman mosaic floors, including a figurative mosaic depicting dolphins. Other mosaics feature an intricately crafted wine mixing vessel and geometric patterns.

Stelzer: “A hidden cultural treasure comes to light”

“The mosaics of Thalheim once again demonstrate the impressive cultural treasures our country holds,” said Governor of Upper Austria Thomas Stelzer (ÖVP). He pointed to Upper Austria’s long history of settlement and its visible traces, such as those along the Danubian Limes and in the Hallstatt region.

The discovery of the mosaics lines up to a series of significant archaeological finds in Upper Austria, but stands out due to its exceptional quality and rarity, particularly the two dolphins swimming through stylized waves, a motif seldom seen this far north of the Mediterranean.

Experiencing science at first hand

Excavation work will continue until June 6. Just a few days later, on June 10, interested visitors will be able to look at the extraordinary finds on-site starting at 1:00 pm as part of the “Open Excavation Day.”

Those wishing to delve deeper into the scientific findings will have the opportunity on June 25: during an evening lecture titled “Münzen, Gräber, Mosaike” (“Coins, Graves, Mosaics”), the results will be presented in detail for the first time.

Future prospects for the mosaics

Plans are already being considered for a permanent display of the finds: the mosaics could become part of the newly designed archaeological exhibition at the Schlossmuseum Linz. Their inclusion in the 2027 State Garden Show in Wels is also possible.
