A treasure chest is a chest filled with treasures. Such boxes could be found in a variety of locations when reliving genetic memories through the Animus or a similar device.
Chests in banks were protected by four armed guards, but those scattered inside cities were usually unguarded, or protected by only one or two guards. Those outside of cities however, such as in the Apennine Mountains, were not guarded at all. In Rome and Constantinople, though not usually directly guarded, nearby archers would attack Ezio if they saw him opening chests on rooftops.
Renaissance banks typically contained two chests, and while they were always guarded by three or four men outside the doors, more guards usually patrolled nearby. Rebecca Crane once stated that although all families owned banks, the Pazzi family owned the most by far, and that breaking into them would be worthwhile. However, guards affiliated with the House of Borgia were assigned to attend the banks containing Codex pages.
Art merchants also sold treasure maps that marked the locations of the chests in an entire city, or in one of its districts, with the maps varying in price. They costed between 150ƒ to 395ƒ in the city of Florence, 150ƒ in the Appennine Mountains, 285ƒ in Monteriggioni, 175ƒ to 240ƒ in Tuscany, 235ƒ to 260ƒ in Romagna, and 485ƒ to 995ƒ in Venice.
Upon liberating the districts in Boston and New York, Ratonhnhaké:ton received the key to all the chests located within the liberated district, eliminating the need for lockpicking. Additionally, he gained the key to all Frontier chests. However, chests located inside forts always required lockpicking.
Certain treasure chests were guarded by dogs. Ratonhnhaké:ton could lure them away using huntingbait, or kill them. Accompanying this, maps that detailed the chests' locations could be purchased from general stores.
Aside from money, chests found in Rome could also contain a variety of trade items. These could later be sold to shops, or traded for other valuable items or equipment. They could vary between common objects, such as jars of leeches, or valuable jewelry.
Chests could also be found in the many lairs of Romulus. Aside from money and valuable items, one special chest per lair could be found in its shrine, which contained one of six keys that unlocked the door to the Followers of Romulus' treasure.
Chests in Constantinople often contained bomb ingredients, replacing trade items.
