Why are Eisleben and Wittenberg called Lutherstadt?

The cities of Eisleben and Wittenberg are designated as Lutherstadt (Luther City) due to their profound historical connections to the life and work of the religious reformer Martin Luther.12

• Eisleben: This city is significant as both the birthplace (1483) and the place of death (1546) of Martin Luther. The houses where he was born and died have been preserved, and the local Saints Peter and Paul’s Church contains the baptismal font used for his christening.2
• Wittenberg: This city is recognized as the site where the Reformation began. It was here that Luther, a professor at Wittenberg University, famously challenged the religious establishment, traditionally by posting his Ninety-five Theses on the door of the Castle Church in 1517.13

In 1996, various sites in both Eisleben and Wittenberg associated with Luther were collectively designated a UNESCO World Heritage site in recognition of their immense historical importance.12
