In my previous post I showed a card of Lutherstadt Eisleben. Luther Memorials in Eisleben and Wittenberg is a UNESCO World Heritage site. The houses in Eisleben where Luther was born (1483) and died (1546) are included in this Unesco site.
As this card is showing both Martin Luther's Geburtshaus and his Sterbehause (birth house and death house), it is definitely UNESCO. Actually I received this second Luther card by surprise, only a few days after the first.
