Deutsche Post has recently added a set of two stamps to the “Lighthouse” series first began in 2004.
Moritzburg Lighthouse was built on a miniature harbor on a land-locked lake in Saxony, near Dresden in the late 18th century. It is adjacent to the Little Pheasant Castle which was constructed by Elector Frederick Augustus III of Saxony who later became King of Saxony.
Lindau Lighthouse was constructed between 1853 and 1856 on Lake Constance and is the southern most lighthouse in Germany. It is interesting in that it has a clock built into the tower.
