The two constituent communities have a history that, according to a documentary mention, stretches at least as far back as the year 639. Potsherds that have been found, which came from a Roman factory near Trier suggest that the municipality may have existed as early as the 2nd or 3rd century AD.
Even older traces of settlement – remnants of a stone wall of a flight castle from Celtic times – can be found on the Hochkessel, the mountain on the other side of the Moselle. On the side of the Moselle facing towards the Hunsrück is a Roman-Gaulish burying ground near Saint Peter’s Chapel (Peters-Kapelle) in Neef.
The sparse remnants of a Roman legion’s garrison outpost can be found in the heights of the Calmont.
Beginning in 1794, Ediger and Eller lay under French rule and were merged to form a single municipality. In 1815 they were assigned to the Kingdom of Prussia at the Congress of Vienna, and once again became two separate municipalities. Since 1877, Eller has lain near the end of the Kaiser-Wilhelm-Tunnel, which begins in Cochem and is named after Emperor Wilhelm I (not his more infamous grandson, Wilhelm II). From the time of its completion until 1987, it was Germany’s longest railway tunnel at 4 205 m. The tunnel is part of the Moselstrecke (Moselle line). Not far from the tunnel portal, and before the Moselle bridge, stands Ediger-Eller railway station.
Beginning in 1946, the two municipalities were part of the then newly founded state of Rhineland-Palatinate. On 7 June 1969, in the course of administrative restructuring in Rhineland-Palatinate, Ediger and Eller were once again merged to form a single municipality.
