This vast brick hall was built around the beginning of the fourth century as an imperial audience hall. Its size was political technology. A ruler receiving petitioners in a space roughly 67 metres long and 33 metres high did not need a sign explaining who held power.
After the Roman period, the structure was absorbed into other buildings and eventually the electoral palace complex. In the nineteenth century, Prussian King Friedrich Wilhelm IV ordered it restored as a Protestant church. It was inaugurated for that purpose in 1856.
Then another transformation followed. Bombing during the Second World War destroyed much of the interior. Postwar reconstruction deliberately left the space comparatively plain, allowing the monumental Roman volume to dominate rather than recreating the nineteenth-century decorative scheme.
So the building has repeatedly been asked to represent authority: emperor, prince-elector, Prussian Protestant monarchy and modern congregation. Each period claimed the Roman shell differently.
The phrase “basilica” can be confusing because in Roman architecture it did not necessarily mean a church. Here the original function was secular and imperial. Christianity came later—and inherited one of antiquity’s most intimidating rooms.
