Martin Luther came to the town in 1498, at the age of 15, to study Latin; during that time, he boarded with the family of Alderman Cotta.
In 1898, a "Lutherkeller" restaurant opened in the Cotta house, and tourists could see two "Luther Rooms" (where the young Latin scholar lived) upstairs.
The Luther Rooms were expanded into a full-fledged museum in 1956, with exhibits that range from costumed mannequins
to paintings and interactive video screens. (Source: Germany for Visitors)
