Wardenclyffe Chimney Wellhead Restoration

Sat. September 19, 2020

9:00 am – 10:30 am ET

No Cost to Attend – RSVP Required


Dear Friends,

A 112-year-old chimney crown designed by architect Stanford White for inventor Nikola Tesla’s Wardenclyffe laboratory is being restored to its original spot on Saturday, September 19 in an event that culminates a renovation project marked by challenges as well as unexpected discoveries.

When TSCW removed the wrought iron chimney crown in preparation for renovations, we discovered that the chimney was in a critical state of damage.  A restoration crew began emergency renovations in February 2020, but work soon halted due to the onset of Covid-19.  When the crew resumed work in June, they made an unexpected discovery of a brick arch built into the base of the chimney.  Historic architects and engineers were consulted and exploration revealed an alcove that is being researched for its purpose and possible link to tunnels that Tesla built beneath Wardenclyffe as part of his experiments in wireless power and communications.

While chimney restoration continued over the summer, volunteers were called in for another emergency project:  brick sorting.  The restoration crew wanted to use as much of the original brick as possible, but the condition of the bricks varied greatly.  Volunteers sorted through thousands of bricks to reclaim those usable for reconstruction and repurposing, including a future brick campaign that would offer supporters a piece of Tesla’s lab and a piece of history. It was a community effort that displays a remarkable pride of place and dedication to preserving not only Long Island history, but world history.

Now that chimney restoration is complete, TSCW will replace the chimney crown, which is commonly referred to as a “wellhead” for its resemblance to the decorative ironwork that was once placed on water wells.  Tesla’s chimney wellhead weighs over 1,200 pounds and on Saturday, September 19, it will be hoisted by crane to the spot it was originally placed in 1902.

We hope you join us online to commemorate this step in our progress and pay tribute to the volunteers and supporters who made it possible.
