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.

In the course of administrative restructuring in Rhineland-Palatinate in 1970, the municipality, along with the others in the Amt of Kelberg, was assigned to the Daun district, which has since been given the name Vulkaneifel.

The municipality's arms might in English heraldic language be described thus: Azure a chaplet of eight roses Or seeded argent, in a chief of the third a cross sable.

Until the conquest in the French Revolutionary Wars, Reimerath belonged to the Electorate of Cologne, which bore the black cross on a silver field seen in the chief of the municipality's arms.

The chaplet on the blue field stands for the municipality's and the chapel's patron saint, Our Lady of the Rosary.
