Obito's Laboratory

This laboratory is located within the Mountains' Graveyard. It was first seen when Madara Uchiha teleported himself and Danzō Shimura's corpse there in an attempt to retrieve Shisui Uchiha's eye. There are many glass containers, each one holding an eye, at least one holds a Sharingan eye, in suspended fluid on a massive wall with the Uchiha clan symbol on top. Sasuke Uchiha is later taken here in order to transplant Itachi's eyes.
