The Stalactite Cave (Tropfsteinhöhle) in Eberstadt is approximately 600 metres long and between one and two million years old. Since 1973 tourists have been shown round it. (It forms part of the Geo-Naturpark Bergstrasse-Odenwald). It contains a rich range of stalactites, including very slender examples and extremely conical stalagmites, flags of calc-sinter, terraces of calc-sinter and crystals. Since the cave remained sealed after its discovery and tours took place from the very beginning using electric light, the stalactites are still predominantly as white as chalk, as opposed to most of the older German caves that are shown to the public, where the use of candles and flaming torches caused the stalactites to go blackish.
