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. There are also some surgery equipments. Both the laboratory's location and purpose are still unknown; however, during the Kage Summit, Madara did mention he liked to stockpile good eyes.
