The 250 metre long stretch of road of the market place forms the main axis of the Upper Town. Even in the early years of its existence the market rights of the Lower Town were relocated here, and a busy weekly market is still held here every Tuesday morning. In former times it was also lively here and when Empress Maria Theresia gave instructions in 1760 that the post route from Paris to Vienna be routed via the market place, the demand for teams of relay horses and overnight accommodation increased. The citizens of Günzburg reacted quickly. Of the 43 houses lining the market place in the second half of the 18th century, 18 were guesthouses.
