The facility designated "Blacksite Cathedral" represents unprecedented architecture combining traditional religious design with advanced electromagnetic containment systems. Primary construction materials include lead-lined concrete, bone aggregate composite, and copper inlay networks.
Lead-Bone Composite: Unprecedented material combining traditional lead shielding with processed bone fragments. Spectral analysis reveals the bone component exhibits non-standard calcium isotope ratios.
Copper Inlay Pattern: Geometric design following principles unknown in conventional architecture. Pattern analysis suggests intentional electromagnetic field manipulation rather than decorative purpose.
Mirror Arrays: 73 precisely positioned mirrored surfaces throughout the structure. Alignment creates complex light reflection patterns converging on the altar platform.
Field measurements indicate the structure functions as a resonance chamber. Copper inlays act as antenna networks, while lead-bone walls provide selective frequency filtering. The combination creates a controlled electromagnetic environment optimized for unknown purposes.
During active use, surveillance equipment detected coordinated electromagnetic pulses emanating from congregation positions. Individual visitors reported auditory phenomena ranging from low-frequency humming to clear speech in unknown languages.
Biometric monitoring of subjects within the Faraday cage showed anomalous bone density fluctuations correlating with electromagnetic field variations.
