In 1780, this spring was set in stone as a token of thanks by Imperial Countess Marianne von der Leyen.

In 1898, a housing was built to contain it, which was renovated in 1910, and on 11 June of that year, the spring was officially recognized as the Lamscheider Stahlbrunnen.

[6] The German blazon reads: Über erhöhtem blauem Schildfuß, darin ein silberner Pfahl, in Silber ein schwarzer Schalenbrunnen mit geteiltem schwarzen Wasserstrahl, begleitet rechts und links von einem roten Krug.

The municipality's arms might in English heraldic language be described thus: Per fess abased argent a fountain basin on a short pedestal sable issuant from which four streams of the same, two each falling into each of two two-handled jugs gules standing on each side of the basin, and azure a pale of the first aligned precisely with the pedestal.

The charges above the line of partition refer to the sour spring – Sauerbrunnen – which was well known even as far back as the 16th century for its good mineral water.
