The Kalterherberg parish church "St. Lambertus" is commonly known as the "Eifel Cathedral" due to its striking twin towers. It was built between 1897 and 1901 by Father Arnoldy.
Traces of settlement at the prehistoric Kakushöhle between Eiserfey and Weyer date back to 80,000 BC. Hunter-gatherer groups of the Neanderthals left behind numerous stone implements of the Middle Palaeolithic epochs and animal bones.
