Obito's Laboratory

Madara Uchiha's laboratory was seen when he teleported himself and Danzō Shimura in an attempt to take out 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. These eyes were most likely collected during the Uchiha Massacre, since Madara is never shown collecting them at any other time. There is also some surgery equipment. Both the laboratory's location and purpose are still unknown; however, during the Kage Summit, Madara did mention he liked to stockpile good eyes. Sasuke Uchiha is taken here when he receives Itachi's eyes.
