This is a huge building originally built between AD 306 and 337. It was repurposed into a Protestant Church by the Prussians. The squares in the ceiling are each large enough to hold a Volkswagen beetle

The reason to visit this structure is not its beauty but its historical significance. Apparently, this is the largest building north of the Alps (or possibly all of Europe) from Roman times still standing without any internal supports (67 meter length, 26 meters wide and...More

Some might find this building boring but for me it was impressive. We were also lucky someone was playing the organ at that time. Always extra special in a church if you ask me.

The organ in the back of the church over the entrance is huge. The guide was great in the history he provided and some pictures of the changes made. A must stop if in town.

The Basilica -- the largest single-room structure surviving from Roman times -- is a truly impressive testament to the majesty of the Roman Emperor. It's impossible to not be impressed by this site.

Built around 310, the structure was designed to express the magnificence and might of Constantine I the Great. The massive space; 27 m (90 ft) wide, 33 m (108 ft) high, and 67 m (220 ft) long, was initially the emperor's throne room where he...More

The high ceilings and the size of the building is impressive - it is one large room with no supporting columns. It is simple in comparison to the Dom but the exhibition and the history is well worth a visit.
