After Peter Parler's death in 1399 his sons, Wenzel Parler and particularly Johannes Parler, continued his work; they in turn were succeeded by a certain Master Petrilk, who by all accounts was also a member of Parler's workshop. Under these three masters, the transept and the great tower on its south side were finished. So was the gable which connects the tower with the south transept. Nicknamed 'Golden Gate' (likely because of the golden mosaic of Last Judgment depicted on it), it is through this portal that the kings entered the cathedral for coronation ceremonies.
