Last Tuesday I got two postcards from Germany.
One of them shows the Dechen Cave in Iserlohn. The Dechen Cave was discovered by two railway workers in 1868 and is today one of the most visited show caves in Germany. As the cave was discovered by railway workers, it was owned by the railway for more than hundred years and even got its own train station. The German Cave Museum was opened next to it in 2006.
I got this card a few weeks ago in a cover.
Water Lily (issued 11-05-2017)
with a special postmark about the 150th anniversary of the discovery of the Dechen Cave
To commemorate the discovery anniversary a prepaid cover was also issued.
Thank You very much Stefan for sending me the card in an envelope!
