Anyone who wants to lie at the feet of the Roman emperors in Trier 1,700 years after their audiences has to descend deep. He has to go into the otherwise inaccessible excavations beneath today's Constantine Basilica in order to discover the beginnings and magnificent prehistory of this Roman audience hall. He has to go into the locked Cryptoporticus, an underground corridor that once belonged to a luxurious villa in what would later become the imperial district. And he has to roam through the supply corridors of the Kaiserthermen, where water and workers are supposed to support bathers in their sports and wellness program. With emphasis on should. It's not just the Kaiserthermen that hold a well-kept secret, but also all the underground places that you will explore in small groups during this exclusive tour.
