At Kohlgasse 7, Arnstadt can boast one of the most important homes of the Bach family. In no other Bach venue in Germany has a house survived which is so directly connected with Johann Sebastian Bach, which he frequented and where he probably even lived.
The front part of the property at Kohlgasse 7 was built after the great town fire in 1581. In an “Alimentation Contract”, the baker’s widow Elisabeth Kannewurfin, who owned this property before 1687, left the house and some fields to the court musician Johann Christoph Bach, the twin brother of Johann Sebastian Bach’s father. When the young J.S. Bach came to Arnstadt at the age of eighteen, his uncle had already died. The house was occupied by his aunt Maria Elisabeth Bach with her children, including Johann Ernst Bach, who was not only a close relative but also a close friend of Johann Sebastian. It was this cousin who stood in for J.S. Bach in the New Church when he was in Lübeck. The house was owned by the Bach family for 45 years and served as a meeting point for all the family members.
