Obito's Laboratory

This laboratory is located within the Mountains' Graveyard. It was first seen when Tobi teleported himself and Danzō Shimura's corpse there in an attempt to retrieve Shisui Uchiha's eye, and where Tobi transplanted Itachi Uchiha's eyes into Sasuke.

There are many glass containers, each one holding a Sharingan eye, which are in suspended fluid on a massive wall with the Uchiha clan symbol on top.
