Brigatata

"As I perceive it, the Brigatata was built by the first Sage of Enlightenment. When I say he "built" it I do mean that, as it was created through his ability to re-form matter. The purpose of this structure was to "count" the timeline of Earth, like the Mayan Calendar. Yet the Brigatata was in a way a computer, as each large stone of it's outer wall was inscribed with magnetically charged symbols that responded to the galactic 'Serpent' time wave."

Creation
So as the serpent undulated, the magnetic symbols responded and sent a charge into the core of the Brigatata structure which was composed of a very dense manganese or, which is a form of manganese and received that it has powerful Ascension frequencies. However the manganese core of the Brigatata was not Rhodochrosite. It was far denser than any manganese that anyone have been able to obtain on the surface of this planet. The first Sage's manganese came from the deeper interior of this planet. From what Gaoh was told, very dense manganese stores more precisely the impressions of the undulating Serpent time wave. All manganese to some extent is a 'time counter'. This means that it records time: what we perceive as past, present and future.

The True Purpose of the Brigatata
As passed down through word of mouth, the purpose of the Brigatata then was to register time, and in doing so, affect time. It was actually built to correct the time that was disrupted by. He was attempting to stabilize the pinpoint black holes which had been created with these types of ninjutsu. Aside from its time correcting abilities, the Brigatata is a fortress of solitude, and is completely impervious to outside damage. Even the most powerful of offensive attacks would not suffice. However, the material used can be damaged by a "pin point" attack. The fortress creates a field nearly 3km in diameter rendering Space-Time ninjutsu null. Thus achieving its purpose, as a tool to correct time as we know it and to stop the abuse of these types of techniques. Out of all of Gaoh's tools, the Brigatata is by far the largest and most taxing on him to utilize.
