Porubský bludný balvan, Natural monument in Poruba, Czech Republic
The granite boulder measures 370 centimeters along its longest axis and contains visible pink potassium feldspar crystals ranging from 1 to 2 centimeters.
Initially discovered in 1928 in the Doly area near Porubka stream, local teacher Josef Hurnik arranged its relocation to the village square.
A commemorative plaque placed on the boulder in 1928 carried the inscription 'Harmony in the community, peace in the state' until its removal during occupation.
The illuminated boulder rests on a stone bed surrounded by steel plates at a memorial site on Vresinska Street, accessible to visitors.
With a weight of nearly 11 tons, this erratic boulder contains minerals including plagioclase, crushed quartz, biotite, magnetite, apatite, and titanite.
