Built between 1493–1502 by Benedikt Rejt during the reign of Vladislav II, the hall was the largest secular space (62m × 16m × 13m) in medieval Prague[1] and is among the most complex structural and architectural spaces of the late Middle Ages.
In particular, the construction of the complex stone vaulting system spanning 16m was a refined engineering feat.
The third and highest floor of the palace, the hall replaced a group of rooms dating from the 14th century.
Immediately underneath, the second floor is a Gothic addition built during the reign of Charles IV, Holy Roman Emperor in the 14th century, while the lowest, first floor is a Romanesque palace.
The hall was used for banquets, receptions, coronations, and other events of the Bohemian court.
