cover from Germany

Today I got not only four postcards but also two covers from Germany.

Stamp:

Peony (issued 04-12-2014)

Inside were three postcards.
Two of them show traditions of the Ore Mountains.

The third card shows the Frohnauer Hammer. The Frohnauer Hammer is a hammer mill in Saxony and an important witness to proto-industrial development in the Ore Mountains. The Frohnauer Hammer seeks as part of the Mining Cultural Landscape Erzgebirge/Krušnohoří for the inclusion on the UNESCO World Heritage List.

EDIT:
The Erzgebirge/Krušnohoří Mining Region is one of the new UNESCO World Heritage Sites of 2019.

Thank You very much Jeannette!
