So what did Nikola Tesla figure out and what have they been hiding from us?

And you know who got Tesla's papers right? The ones the government didn't confiscate? 

John Trump (President Trump's uncle) who was a legend at MIT. 

The question is not what Tesla believed about old buildings. The question is what he found in those buildings that convinced him. Tesla did not theorize in the abstract. He worked from measurement, experiment, physical demonstration. If he became convinced that Gothic cathedrals and neoclassical civic halls were electrical infrastructure, it was because he measured something inside them that standard architectural history does not explain.

What did he measure?

In 1934, Nikola Tesla traveled to Paris for a series of lectures on high-frequency electrical phenomena. While in the city, he requested access to Notre-Dame Cathedral — not to admire the rose windows or the flying buttresses. He wanted to examine the crypts and foundation level. The request was approved under the pretext of acoustical research. Tesla spent four hours below the cathedral, alone except for a custodian, examining limestone blocks and metal anchoring systems embedded in the foundation walls.

He returned to New York and immediately wrote to the Rockefeller Foundation requesting funding for what he called acomprehensive survey of pre-modern civic architecture across Europe and North America. The request was denied. No reason given.

But in private letters to Arthur Matthews, Tesla described what he had found beneath Notre-Dame: copper grounding systems embedded directly into the cathedral’s foundation blocks — not modern restorations added during 19th-century repairs, but original construction. Deliberately insulated with natural resins. Geometrically arranged in radial patterns extending outward from the central nave. Still conductive after six centuries.

Tesla called themearth batteries— passive electrical storage systems using the compression of stone, the mineralization of groundwater, and the conductivity of copper to create standing charges that could be drawn upon without fuel, without generation, without metering.
