There is an interlaced
hexagram on the mosaic pavement of the
4th-century Basilica of St. Quirinus in Szombathely, Hungary. In the
Roman times this city was called Savaria and it was the capital of Pannonia. The mosaic pavement was discovered during building work in 1938.
A semi-circular apse and a 25m (82ft) long mosaic (acanthus ornaments, Christian symbols) by a master from Aquileia have been preserved from the St Quirinus basilica (4th C), which was rebuilt from parts of the former governor's palace.
