Gian Giacomo Poldi Pezzoli was an important collector of arms and armours. The Armoury was the first room of the House-Museum to be created. It was originally located on the first floor. Conceived in a Neo-Gothic style, the room was designed between 1846 and 1851 by the set designer Filippo Peroni (who worked for La Scala Theater), with stuccoes by Paolo Gazzoli and stained-glass by Pompeo Bertini.
The effect was definitely theatrical with standards, arms, armours, trophies, showcases crowding the room. Following its destruction due to the last world war, the Armourywas transferred to the ground floor where it is today.
The new (2000) display of this room is the work of the famous Italian sculptor Arnaldo Pomodoro (born in 1926): an amazing, austere setting in which each item seems suspended in a timeless space.
