Top 7 Caves ハルシュタットでの

Addendum to Naxxos from February 20, 2021: The sand was used as writing sand (also called blotting sand or quenching sand). It was formerly used to dry wet ink. Medieval inks dried more slowly than modern inks. ... Traces of blotting sand can still be found on many handwritten historical documents. (Source: Wikipedia)

You can take a look

Old rock cellars in the mountain

Nicely situated in a depression next to the path. In front of it is the large wooden cross.

Unfortunately it was closed, but I was able to take a look inside

The geological subsoil of the Bamberg mountain area is Keuper sandstone. Sand extraction has been in operation since the 11th century, and this continued well into the industrial age. In the 17th and 18th centuries, the rock cellars were used to store wine and later beer and malt. During the 19th century more tunnel systems were added, resulting in a tunnel system almost 10 km long. In 1941, the underground tunnels were expanded for air raid protection purposes.

I spotted them in passing! I'm traveling slower than the cyclists 🙂 A small cave with white sand and the entrance is almost hidden by ivy vines.

It's so beautiful here on the Main! Just go and enjoy...
