Today I got a nice postcard from Germany! The postcard features multiple views of the city of Bad Pyrmont, which is located in Lower Saxony. Located along the River Emmer, it was once a famous spa resort in the 17th and 18th centuries. The city's main attractions include its 16th century baroque castle, a unique vapor cave that releases carbon dioxide, and its famous palm park. The postcard is an official Postcrossing card, DE-3237885. Thanks Cristine!
