The Bing Cave or Binghöhle is a limestone show cave in Wiesenttal, Bavaria, Germany. It was discovered in 1905 by the Jewish industrialist, poet, memoirist, and amateur naturalist Ignaz Bing (1840–1918), co-founder with his brother Adolf Bing of the Gebruder Bing toy and household goods company in Nürnberg.
After years of exploration in the region, Ignaz Bing discovered a beautiful stalactite cave in 1905 near the town of Streitberg (Wiesenttal). Using his own wealth, he purchased the land from the local forester who owned it. The earliest excavations at the mouth of the cave, designed to widen its access, uncovered prehistoric artifacts and fossils, which Bing and his workers carefully removed and catalogued.
In 1906, Bing installed electric lights and turned the cavern into a tourist attraction. He hired Konrad Arndt, who had worked on the initial excavations, as the site's overseer, and his niece, the enthusiastic amateur spelunker Olga Hirsch, worked as a guide. In 1909 a movie crew toured the cave and the resultant film was screened at the "cinematograph salon" of the Noris Theater in Nürnberg. The site soon became so popular that Bing personally conducted a private tour of the cave for Prince Ludwig of Bavaria.
When it was first opened to the public, the Binghöhle originally had a length of about 230 meters. In 1913, a passage was carefully excavated around one of the grottoes to make a further gallery accessible. In 1928, the lighting, which had been run from a private generator, was connected to the national electrical grid. In 1936 another 70 meter long path was discovered and connected to the main gallery. The Binghöhle reaches a depth of 60 meters below the surface. It follows the path of a now-dry underground river that once flowed into the then-higher Wiesent River.
As with most tourist caves, the various features have been named. Among these are the Stalactite Gallery, the Kellermann Cave with its Giant Pillar, the Hall of Candles, the Grotto of Venus, the Catacombs, the Shell Rock, Olga's Grotto, the Nixie Grotto, the Fantasy Cave, the Prince Ludwig Grotto, the Three Peaks, and the New Department.
