I’ve previously mentioned how Aix la Chapelle, or Aachen, was the original capital of the holy Roman Empire founded by Charlemagne in 800. As befits an Emperor, the cathedral built for Charlemagne, completed around 805, is even today quite magnificent.

The interior is painted or marbled in magnificent fashion, which quite took my breath away on a recent visit. Of course, the original cathedrals were decorated both inside and outside. Here at least the interior decoration remains, giving a taste of just how impressive these buildings originally were. And just imagine the collective dedication and money that has gone into maintaining such an edifice over more than twelve centuries.

Here are just four photographs (as slideshow) to give a brief impression. You just have to go there for the experience.
