The reign of the last member of the Jagiellonian dynasty, Sigismund I the Old, was a high point in Wawel fortunes. Following another fire in 1499, from 1507 to 1536, Sigismund rebuilt the royal residence. King Sigismund had spent part of his youth at the court of his brother, King Vladislaus of Hungary and Bohemia in Buda; this court has a small band of Italian artisans pioneering the Renaissance movement, at that time little known outside of Florence. Thus inspired Sigismund took the decision to rebuild in the Renaissance style within the walls of the old castle. A great influence on the king was his second wife, Italian-born Bona Sforza. She brought in the best native and foreign artists including Italian architects, sculptors, and German decorators, to refurbish the castle into a splendid Renaissance palace.
