On Friday I got a postcard from Germany.
It shows a map of lighthouses on Schleswig-Holstein's North Sea coast.
I bought this card in Büsum last year.
With a matching stamp:
Lighthouses (from set of two) (issued 07-07-2016)
with a special postmark showing also the Kampen Lighthouse
The Kampen Lighthouse is located on the highest elevation of Sylt. It was first lit in 1856, when the island was a part of Denmark.
