On the first floor there are private royal apartments, chambers for court members and guest rooms. Four chambers located to the south of the Envoys’ Stairs were designated for the King’s guests. In this part of the palace there are original larch wood ceilings and, also original, painted wall friezes in two of the rooms. In terms of architecture especially noteworthy are the Gothic and Renaissance portals – the artwork of Maestro Benedict. The Renaissance furnishing includes northern European and Italian artwork, including the tapestries with grotesque, landscape and animal themes from the collection of Sigismund Augustus. The last two rooms boast Italian paintings from the old collection of the Lanckoroński family. Over sixty paintings from this collection form a studiolo in one of the rooms in Jordanka, the Gothic tower.
