The Assassin Tombs were six hidden tombs or shrines dedicated to several notable proto-Assassins and located across Italy between at least 1290 and 1486.
Built by members of the Italian Brotherhood of Assassins as dedications to the lives of their residents, each crypt contained a wealth of treasure, and a statue of the Assassin who was being dedicated. Furthrmore, inside each tomb lay an Assassin Seal, which, when brought together with the other five, unlocked a secure gate in the Sanctuary, beneath the Villa Auditore. Beyond the gate, the legendary Armor of Altaïr could be accessed.
Florence and San Gimignano
There were three tombs within the regions of Florence and Tuscany. The first was located within the catacombs of the Santa Maria Novella, and was discovered by the Assassin Ezio Auditore da Firenze in 1478, while he was trying to eavesdrop on a Templar meeting. This tomb was the resting place of Darius, slayer of Xerxes I of Persia.
The third tomb was within San Gimignano, and was built atop the Torre Grossa, although entrance to the tomb was only possible by passing through the city's Palazzo Comunale below. This tomb was the resting place of Wei Yu, who had assassinated the first Emperor of China, Qin Shi Huang.
Forlì and Venice
The other two lay in Venice; within the district of San Marco, the eponymous Basilica di San Marco housed a cenotaph of Amunet, who had been responsible for the death of Cleopatra and whose remains actually rested in Egypt.
Built in Monteriggioni during the late 13th century, the Auditore Family Crypt was constructed by Domenico Auditore to serve as the resting place of Domenico and his son. The story of Domenico's life was inscribed across the walls along the pathway, from the main entrance to the crypt itself.
During the 15th century, Domenico's great-great-grandson Ezio Auditore explored the crypt and learned of his family's history and its involvement with the Assassins.
Armor of Altaïr
- Main article: Armor of Altaïr
Obtaining all Assassin's Seals unlocked Altaïr's armor, a suit of armor with the highest defense obtainable. Altaïr created the armor using his Apple of Eden, to make it invulnerable to many weapons and dangers. Dyes purchasable from tailors were not visible upon the armor, save on the inside of the hood.
