HBO filmed The Gilded Age Season 4 across New York through spring 2026 — in Manhattan, Harlem, Queens and Staten Island. Production locations are not announced, so every sighting below was found and reported by viewers on r/thegildedage: parking notices, dressed sets, period props and character trailers spotted in the street. Each one is credited to the person who found it and links back to their original post.
E 26th–28th St between 5th Ave & Park Ave South, NoMad85% confidence
An official HBO production parking notice went up on 18 March 2026, covering several blocks around Madison Square for filming five days later on 23 March — the earliest Season 4 sighting on this map.

10 St. Nicholas Place, Hamilton Heights35% confidence
In March 2026 a fan flagged the landmark 1888 Bailey mansion as a possible Season 4 exterior, spotted in person rather than photographed. HBO hasn't confirmed it, but the block sits close to the corroborated Sugar Hill filming nearby, and intact 1880s mansion facades are scarce anywhere else in Manhattan.

15 E 27th St, NoMad35% confidence
A fan identified the Beaux-Arts ballroom at 15 E 27th St as a possible Season 4 interior in March 2026. HBO hasn't confirmed it and nobody has photographed filming there, but the venue's intact period ballroom and its spot inside the show's Madison Square cluster make it a plausible pick.

E 27th St & Park Ave South, NoMad80% confidence
A fan photographed character trailer #9 at this NoMad corner on 23 March 2026, its door plate reading Oscar van Rhijn, with neighboring trailers marked for Kate and Salli. It's one of the few Season 4 sightings that names a specific character rather than just a filming site.

Sugar Hill, Harlem85% confidence
Two Reddit users independently reported Season 4 filming in Sugar Hill — one photographing the production, the other describing a week-long shoot centered on a townhouse on Convent Avenue. That overlap with the neighboring Convent Avenue sighting makes this one of the map's better-corroborated leads.

Near 80th St & Cooper Ave, Glendale, Queens30% confidence
A Queens resident reported Season 4 crews returning to the same residential block near Atlas Park on repeated Thursdays and Fridays over several weeks in early 2026. The area's early-1900s brick rowhouses fit the production's pattern of scouting outer-borough streets that read as period with little extra dressing.

318 Convent Ave, Hamilton Heights95% confidence
A fan watched crew unload furniture labeled "Peggy NY house" into a Convent Avenue brownstone in March 2026 — the clearest identification on this map of which character's home a location represents. A second sighting two blocks away in April corroborated the same stretch of Hamilton Heights as an active Season 4 set.

55 Water St, Financial District90% confidence
An official three-day parking notice for production "TGA" went up outside 55 Water Street in mid-May 2026, one of two downtown permits that surfaced the same weekend. Photographed by a passerby, it places filming squarely in the Financial District's surviving 19th-century waterfront blocks.

1000 Richmond Terrace, Staten Island75% confidence
A visitor spotted a "TGA" production sign posted at Snug Harbor Cultural Center & Botanical Garden — the first Staten Island sighting reported for Season 4. Snug Harbor's row of Greek Revival dormitories, raised between the 1830s and 1880s, gives the production a self-contained campus of period architecture.

South William St, Mill St & Stone Street, FiDi95% confidence
A fan photographed several blocks of Financial District streets dressed for Season 4 — period flags, reproduction theater bills and patent-medicine posters papered across South William, Mill and Stone Streets, with crew and equipment visibly in place. The scale of the dressing suggests a major street scene rather than a quick pickup shot.

Whitehall St near the Staten Island Ferry Terminal, FiDi88% confidence
A commuter spotted a "No Parking — Film Shoot" notice for "TGA" posted near the Whitehall St–South Ferry subway stop in mid-May 2026, the same weekend a matching permit appeared at 55 Water Street a few blocks north — together pointing to a coordinated multi-day shoot along the historic ferry district.
