Aula Palatina, Trier, at dusk

This is Basilica of Constantine. A remarkable trace of the Late Roman Empire, when Trier (Augusta Treverorum) was capital of the North-Western Provinces, so that the Augustus could command the Rhine Frontier.

The building's sheer size is impressive, and although heavily restored in the 19th Century when the Bishop's Palace was removed, and bombed in the 20th Century, its survival gives us a unique impression of the might of the Later Roman Empire.

It was constructed as the audience chamber of Constantine's Palace in Trier in c310, after Constantine had become Augustus of the Gallic Prefecture consisting of the dioceses of Britannia, Galliae, Septem Provinciae and Hispania. He subsequently conquered Italy and the East moving his capital to Rome and then to his new City of Constantinople.

The Aula Palatina is 67m long and has a roof span of 26.05m which makes it the largest extant hall from antiquity.

It is now a Lutheran Church.
