Limburg Basin

The hills that rise at the edges of the basin or within it form landmarks that are visible from a long distance away, dominating the landscape.

In the north, the terrain is shaped by the younger volcanism of the Westerwald with individual basalt deposits - the Galgenberg (241.8 m) at Hadamar, the Großer Berg (245.3 m}) at Ahlbach, the Beselicher Kopf (296 m}) at Obertiefenbach.

These are related to tectonic distortions, which pass through the basin in a north–south direction and are recognizable by the Weitungen at Dietkirchen and Limburg as well as by ditch fillings (sand, gravel, clay).

The black earth-like soils, together with the favourable climate of the basin, have resulted in an important old settlement area with intensive corn and root crop farming.

Not to be underestimated is the historical importance of the basin for road communications as there is a key crossing over the Lahn at Limburg, used by long-distance trading routes of the early Middle Ages.
