Pain's Tower

This is the tallest tower in Amegakure and was also Pain's base of operations. It has four humanoid faces at each side and is connected to two smaller towers. The faces that Pain sat on the tounge looking out over the city is depicted with a pipe and has piercings, with its tongue stuck out. Somewhere inside is a chamber hidden behind a solid wall where the Six Paths of Pain are stored when not in use. At the base of the tower, members of Pain's forces deliver bodies. Its height allows Nagato to transmit chakra signals to the Paths regardless of their position in the city.

Trivia
