A second reception stairway, the Senators' Staircase, of the Wawel Castle was constructed between 1599 and 1602 by Giovanni Trevano and Ambrogio Meazzi in the north-west corner of the castle. It is the first such modern construction in Poland facilitating the communication between the floors of the residence and located in the interior space of the edifice. Marble stairs do not run steeply, as it is in the Renaissance Deputies' Staircase, but break up regularly in the middle floors with comfortable podests. Early baroque portals of the saircase with auricular elements designed by Trevano were executed in greenish Carpathian sandstone by Meazzi. The Summary of the Royal spendings by the Kraków's supevisor Franciszek Rylski of Ostoja coat of arms from 1599 and 1600 in the Central Archives of Historical Records in Warsaw (I 299), records a spending of fl. 2991 gr. 15 den. 12 "for demolition of the old stairs and construction of the new one, for Italians and different materials" and salaries of "Jan Treurer (Giovanni Trevano), mason ad r[ation]em fl. 1300 datum fl. 1250" and "Ambrosio Meaczi (Ambrogio Meazzi) to inlay the stairs and doors ad r[ation]em fl. 500 datum fl. 300".
