Basilica of Constantine (Aula Palatina)
Konstantinbasilika
The palace throne hall built by Constantine the Great in the early 4th century. Its column-free interior, 67 meters long and 33 meters high, is the largest surviving Roman single-space hall.
The Basilica of Constantine was originally the audience hall of the Roman emperors in Trier. Built of red brick on an impressive scale, its interior has no columns at all. In the Middle Ages it was incorporated into the bishop’s palace, and in the 19th century it was restored by the Prussian king. It is now the Evangelical Church of the Redeemer. Entry is free, and the large organ inside often hosts concerts. The south side of the hall connects to the pink Rococo Electoral Palace and its palace gardens, and you can walk all the way from here to the Imperial Baths. It is a UNESCO World Heritage Site.
