He was supposed to "convert it into a common town ornament", set up a workshop and warehouse, but was not granted tax exemption.
At the beginning of September 1588 Nosseni went to Italy in order to get sculptors, founders and stonemasons for the monumental building at Freiberg.
On 23 October he arrived in Florence, where he recruited Carlo de Cesare, who later cast the bronze statues in Freiberg.
On the way back via Modena he acquired 180 painted and gilded shields (rondelles) for the stable building and in Venice 600 crystal glasses from Murano for the Dresden court.
In 1607 Count Ernst von Holstein-Schaumburg began planning his princely mausoleum at Stadthagen and commissioned Nosseni to design it.
However, the construction of the building did not begin until the year of Nosseni's death in 1620 and was carried out by his pupil Anton Boten.
