Considering the Mercure Atrium Braunschweig in Braunschweig?
A VT member wrote the following comment about visiting Braunschweig:
The Dom by Colzy
This is presently a Protestant Lutheran cathedral and was erected by Henry the Lion during the years 1173-1195. Henry the Lion chose the church as his place of burial and was buried there in 1195 next to his wife Mathilde. The tomb of the Duke and Mathilde in the nave of the cathedral originates from around 1250 and is made of muschelkalk and is therefore considered an important work of medieval stone sculpture.
