Bükkszenterzsébet, Nagy-kő The Oligocene - Lower Miocene, which builds the Heves-Borsod Hills, is a well-lit, strongly drained, shallow-water sandstone builds the cliff of the Nagy-kő in Bükksenterzsébet. In some parts of the shallow sea, the rivers transported large amounts of sediment - sand, gravel. The deposited material was piled up by watercourses and sea currents, causing the rock to appear cross-bedded. The shallow beaches were home to large, shell-like mussels that could withstand the intense flow. The thick sandstone sequence was cut and elevated by structural movements. The sandstone were elevated until the surface and was destroyed and further modified by climatic influences. The steep sandstone hill of the Nagy-kő in Bükkszenterzsébet has been shaped and shaped by its current form due to precipitation, wind and temperature fluctuations.. The southern ,south-east side of Nagy-kő i surrended by a massive arched, 60-80 m high, almost vertical rock wall, but its eastern and western sides are very steep. At the top of the Nagy-kő was once an earth castle, its remains of which can be observed today. At the height of the saddle there is a low, 82 m long, 1 m wide earthen mound, now only 10-20 cm high.. The fortress and its adjoining edges delimit the former settlement, which is classified among the fortified colonies of the late Bronze Age Kyjatice culture (i.e. 12th-7th centuries) based on the location of the mountain and the nature of the fortification.
