The municipality lies in the Vulkaneifel, a part of the Eifel known for its volcanic history, geographical and geological features, and even ongoing activity today, including gases that sometimes well up from the earth.

The placename “Dreis” is obviously derived from the Old High German word triusan (“bubble”, “gush”).

The two then separate municipalities once belonged to the Counts of Manderscheid, who held the County of Kerpen, and eventually ended up with the Duchy of Arenberg after an hereditary division of holdings.

Three youths, Helmut Keul, Ernst Josef Probst and Werner Ullrich, went to the Dreis munitions depot to undertake the disarming of the weapons there, left over from the war.

[4] In a written announcement from 28 August 1968, the Daun Amt and town administration stated “the proposal for a fourth law about administrative restructuring in Rhineland-Palatinate presented at the Landtag and already consulted in First Reading provides for the local area the amalgamation of, among others, the localities of … Dockweiler, Dreis and possibly also Brück”.

On 20 April 1969 the Mainz Ministry of the Interior published a decree about the formation of Verbandsgemeinden in the Regierungsbezirke of Koblenz and Trier.

On 15 August 1977, the Trier Regierungsbezirk administration granted the municipality of Dreis the new name Dreis-Brück.

Moreover, the fountain also refers to the municipality's status as the site of a state-recognized health spring, the “Vulkania Quelle” in Dreis.

Even his alter ego, Siggi Baumeister, the fictional protagonist of his Eifel crime stories, lives in Dreis-Brück.
