Often regarded as the first Renaissance church in Germany, the rather plain-looking (and well-hidden) St Anna Kirche is accessed via a set of cloisters lined with tombstones. The church contains a bevy of treasures, as well as the sumptuous Fuggerkapelle, where Jacob Fugger and some of his relatives lie buried, and the lavishly frescoed Goldschmiedekapelle (Goldsmiths' Chapel; 1420).
The church played an important role during the Reformation. In 1518 Martin Luther, in town to defend his beliefs before the papal legate, stayed at what was then a Carmelite monastery. His rooms have been turned into the Lutherstiege, a very informative exhibition about the Reformation and Luther's life.
