Scharfenstein is a 304 metres (997 ft) hill composed of basalt in the Schwalm-Eder-Kreis district of North Hesse, Germany.

It is likely that after eruption or intrusion, the basalt slumped back to produce the outcrop features at Scharfenstein.

Between the 21 and 22 March 1865, as the result of weathering, especially repeated freezing and cracking, the original outcrop broke apart and was reduced in height by a half.

In 1838, Franz von Dingelstedt published a collection of poems, one of which was entitled 'Althessiche Sage' (English: old hessian legend).

[3] It tells the romantic story of a band of Roman warriors, who, after being defeated in battle by the German barbarians, ask for sanctuary.

At Scharfenstein, at midnight hour, Are mystic tones revealed, Like tramp of war-steeds, and shield.

Why, the doors Assail tumultuously, Till Scharfenstein moves circling round, And caverns open fly?
