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.

Steineberg lies south of the High Eifel, some 20 km north of the Moselle valley, near the district seat of Daun.

The municipality's arms might in English heraldic language be described thus: Argent a pile transposed throughout vert charged with three stones of the field, one resting on the other two, dexter a sword palewise gules, the hilt to chief, and sinister a dove of the last.

The “pile transposed” (that is, the wedge-shaped charge) stands for the Steineberger Ley, the 560 m-high volcanic cone that defines the local scenery.

On this mountain, the Celts built a defensive wall out of basalt stones and logs that served the local people as a refuge castle.

The sword on the dexter (armsbearer's right, viewer's left) side is meant to stand for the so-called Schwedenschlacht (“Swede Battle”) in the Thirty Years' War, which was supposedly fought near the Steineberger Ley.

The tinctures gules and argent (red and silver) stand for Steineberg's former allegiance to the Electorate of Trier as part of the Amt of Daun.

This mountain on Steineberg's southeast outskirts, which can be seen from afar, and which stretches to the neighbouring municipality of Steiningen, is important to history and tourism.

The 28 m-tall tower rose with the help of subsidies from the European Union, the state of Rhineland-Palatinate, the Verbandsgemeinde of Daun and the Daun/Vulkaneifel Economic Promotion Organization (Wirtschaftsförderungsgesellschaft Daun/Vulkaneifel).

Given its outstanding location above the Steineberger Ley's treetops, visitors can on a clear day see far across the Eifel and the Moselle valleys, and even make out the Nürburgring some 20 km away.

Broken-down walls made of mortarless masonry and artificially steepened sides hem a gently sloping inner area of 2.2 ha.

Since there have yet to be any archaeological investigations, the complex's age can only be estimated: The size of the area and the wall building method using dry stonework (likely with a wooden truss) would seem to suggest a Celtic castle from the time between 500 and 100 BC.

Today, the overwhelming majority of Steineberg inhabitants work in the service and industrial sectors throughout the Eifel, mainly in Daun, Wittlich or Cochem.
