If you have lived in Shoreham for more than a summer, you know the fence on Route 25A. Chain-link, mostly, with a stretch of trees behind it and a brick building you can just make out if you slow down enough. For over a hundred years, that has been the entire relationship most residents had with Nikola Tesla's last surviving laboratory: a glimpse from the car, a story you half remember about a man who wanted to broadcast electricity through the air and never finished the tower to do it.
That relationship changed on July 11, 2026. For the first time since the site was built, there is a building on that 16-acre property that the public can walk into without a docent unlocking a gate first. It took a fire to get there, and it is worth understanding both halves of that sentence if you want to know what is actually different about the landmark down the road.
The Only Way In Used to Be a Reservation
Until this summer, seeing Wardenclyffe meant booking ahead. As of a June 2026 listing, the site operated on a strict appointment basis: closed Monday through Thursday, open Friday through Sunday from 9:30 a.m. to 3 p.m., and only for docent-led tours reserved in advance. There was no lobby to wander into, no front desk to ask a question at. You scheduled your visit weeks out, showed up at the appointed hour, and a guide walked you through the grounds where Tesla's tower once stood.
That model made sense for a construction site still mid-restoration. It did not make Wardenclyffe feel like a place you could actually stop by.
What Actually Opened on July 11
The Eugene Sayan Visitor Center changes that math. At 2,200 square feet, it is described by Riverhead News Review as the first permanent public building ever constructed on the Wardenclyffe campus, and its purpose is specific: it functions as a preview center for the larger campus, supporting historical tours and docent training that follow Smithsonian standards, while also expanding STEAM programming for nearby schools and libraries.
Executive Director Kara Cannon put it plainly when the dedication was announced, saying this year "marks a truly special moment in our history," and that "the opening of the Sayan Center means we can finally welcome visitors into a dedicated space on this extraordinary site to explore exhibits, experience programming, and begin their journey through Nikola Tesla's last remaining laboratory."
That last phrase matters. The original lab, the brick building designed by architect Stanford White and listed on the National Register of Historic Places since 2018, is still the heart of the site. The Sayan Center does not replace it. It gives you a place to start before you get there.
The Fire That Slowed Everything Down, Then Sped It Up
Here is the part of the story most residents missed if they were not reading the local papers closely. In November 2023, a fire tore through the roof of Tesla's original laboratory, destroying 20th-century steel girders and causing more than $3 million in damage. Construction on the visitor center had already broken ground in September 2025, so the two events were not the same project. But Riverhead News Review frames the July dedication as another milestone in Wardenclyffe's rebuilding effort in the fire's aftermath, which tells you something about how the nonprofit has run its recovery: not as a single repair job, but as a broader push to get more of the property in front of the public sooner rather than later.
| Before July 2026 | After July 2026 | |
|---|---|---|
| Public access | Docent-led tours only, by advance reservation, Fri-Sun | A dedicated visitor building open as the entry point to the site |
| Buildings open to walk-in visitors | None | The Eugene Sayan Visitor Center |
| Original 1901 lab | Original Stanford White structure, tour-only | Still tour-only, but reached through the new center |
| Damage from the 2023 fire | Roof and steel girders destroyed, $3M+ in damage | Restoration ongoing, framed as part of the same rebuilding push |
The Night Shoreham Showed Up
The dedication did not happen quietly. It happened as the centerpiece of the Nikola Tesla Expo 2026, held July 11 from 5 to 9 p.m. on the Wardenclyffe grounds, with a rain date the next day. The timing was deliberate: Tesla was born July 10, 1856, so the Expo doubled as his 170th birthday celebration, and organizers tied the date to Suffolk County's official commemoration of America's 250th anniversary, known locally as Suffolk 250.
The event itself drew the kind of crowd that only a genuinely local institution can pull off. Greater Long Island reported that the 2025 version of the Expo drew thousands from across Long Island, and this year's edition featured hands-on STEM activities, robotics and amateur radio exhibits, live music, and a dedicated Kids Stage. Vendors on the grounds included the Cradle of Aviation Museum, FIRST Robotics, the Long Island Aquarium, and the Custer Institute and Observatory, alongside food trucks, mini-golf, and the kind of summer-fair staples that make a science event feel like a neighborhood one, including Wild Bill's Soda, Kona Ice, and Mister Softee.
The night closed with a choreographed drone light show performed by a team known for its America's Got Talent appearance, tracing Tesla's journey from his immigration to America through the technologies his work eventually made possible. It is a strange kind of full-circle: a man who once imagined broadcasting power wirelessly through the sky, honored a century later by hundreds of illuminated drones doing exactly that above the same 16 acres.
What This Means If You Want to Actually Walk In
None of this means Wardenclyffe has become a drop-in museum overnight. The full transformation into what the nonprofit calls a Tesla Museum is still years out, and the original laboratory remains accessible primarily through guided tours. But the site's public rhythm has grown noticeably fuller. Beyond the annual Expo, Tesla Science Center at Wardenclyffe runs a recurring calendar that has included the Wardenclyffe Science Pub, a Winter at Wardenclyffe holiday fair and STEM market, SpaceHack in partnership with NASA Space Apps Brookhaven, and an "Investigate Wardenclyffe" evening with the Long Island Paranormal Investigators. If you have written the site off as something you can only see from the car, that calendar is worth a second look, and the center's own site is the place to check current hours and reserve a tour before you go.
For a hamlet whose name most people outside Suffolk County only recognize because of the Tesla connection, this is not a small shift. Shoreham has spent decades being the answer to a trivia question about a laboratory nobody could actually enter. That is no longer entirely true. The fence on 25A is still there. But for the first time, there is a door in it that opens.
