In the heart of Aachen’s Old Town, the Chronoscopes stand like silent gateways to other eras. The tall metal steles, each with its own viewing window, invite you to immerse yourself in past centuries through digital reconstructions. Whether Roman bathing culture, the medieval palace, or Baroque bathing splendor—at these points, you get a sense of how the city took shape over the course of time. The installations not only make history visible but almost tangible, as if you were standing among ancient walls that have long since vanished but live on in images.
