Imagined reconstruction of Heidentor (“Heathen’s Gate”), the most impressive surviving Roman monument in Austria.

Carutum web-site:

All that remains now of the former splendid edifice is the famous archway. Latest scientific investigations clearly prove that it was originally erected as a quadrifrons (Greek tetrapylon), a monument with pillars and four archways, which was built from 354 to 361 AD as a triumphal arch in honour of Emperor Constantius II and which rose protectively over the statue of the Emperor.

The name ‘Heidentor’ dates from the Middle Ages when the archway was thought to have been erected by non-Christians and was therefore called ‘heydnisch Tor’ (heathen gate).
