The Tesla Experimental Station[1] was a Colorado Springs laboratory built 1899 on an empty Knob Hill site between the 1876 Colorado School for the Deaf and Blind and the Union Printers Home,[2] where Tesla conducted the research described in the Colorado Springs Notes, 1899-1900.

At this location, in 1899, Tesla, several of his assistants, and a local contractor commenced the construction of Tesla's laboratory shortly after arriving in Colorado Springs. The lab's primary purpose was to conduct experiments with high frequency electricity and other phenomena. Its secondary purpose was for research into wireless transmission of electrical power. The lab possessed the largest Tesla Coil ever built, 49.25 feet (15 m) in diameter, [3] which was a preliminary version of the magnifying transmitter planned for installation in the Wardenclyffe Tower. This coil reproduced the effects of lightning and its accompanying thunder for the first time in history. On January 7, 1900, Tesla's lab here was torn down, broken up, and its contents sold to pay debts when Tesla left Colorado Springs.
