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.

South of Esch lies a war graveyard witnessing the heavy fighting in March 1945.

The German blazon reads: In Rot das goldene Brustbild des hl.

Über einem goldenen Schilde, darin ein rotbewehrter schwarzer Löwe, belegt mit fünflätzigem, roten Turnierkragen.

The municipality’s arms might in English heraldic language be described thus: Gules, in base an inescutcheon Or charged with a lion rampant sable armed and langued gules and surmounted at the shoulder by a label of five points of the same, standing behind the inescutcheon Saint Peter in his glory, vested Or and turned to dexter, in his dexter hand a book argent and in his sinister hand a key palewise of the same, the wards to chief and dexter.
