Construction and conception
Initial sketches for the palazzo were completed by Leone Battista Alberti, but the actual plans were completed by the building's commissioner and owner, Giovanni Auditore da Firenze. These included secret passages and rooms where Giovanni could perform his Assassin duties.
The building was completed in 1473, but in 1476, the Auditore family was executed and the building was abandoned, apart from a contingent of Florentine city guards stationed along the palazzo's roof, presumably remaining on the lookout for the lone surviving Auditore, Ezio. These guards were removed upon the failure of the Pazzi conspiracy, leaving the palazzo completely abandoned.
The palazzo was once again briefly occupied in 1494, when French troops invaded Florence and ousted Piero de' Medici. The occupying French troops used the palazzo as a billet, until departing to conquer the Kingdom of Naples. The palazzo was stripped of its remaining contents during the Bonfire of the Vanities. It was at this time that Ezio revisited the palazzo, where he experienced a ghostly vision of his family.
Between 1498 and 1500, rumors of the palazzo's destruction had reached the surviving Auditore in Monteriggioni. Once Ezio had arrived in Rome in January 1500, Niccolò Machiavelli confirmed that the palace had been demolished.
- In Assassin's Creed II, the database entry for the Palazzo Auditore inaccurately described it as "a fixture of the Santa Maria Novella district" instead of the San Giovanni district.
- During the Cristina memory "Last Rites" in Assassin's Creed: Brotherhood, the door to Giovanni's office was open and could be entered. In Assassin's Creed II, this area was inaccessible.
- In the same memory, however, the door leading to Giovanni's hidden room was inaccessible, and the secret entrance could not be seen, even with Eagle Vision.
- In the novelization of Assassin's Creed: Brotherhood, the Palazzo Auditore was referred to as the "Villa Auditore". Likewise, the Auditore villa in Monteriggioni was referred to as "Mario's Citadel".
