This bit of architechture is a famous landmark in Nürnberg, Germany; it is called a chörlein. This one was built in 1513. Looks to me like an elaborate 3-sided bay window held up by an elaborate stone column attached to the side of the house. This house is where the pastor lived.
The other building in the background is the St. Sebaldus church, the one Maria Sybilla Merian Graf attended, and where her second daughter, Dorothea, was baptised.
