WINTERTHUR, Del. (April 27, 2026)—Winterthur Museum, Garden & Library is celebrating the museum’s 75th anniversary with an elegant garden party on May 16 that features a 20-piece big band, a parade down Garden Lane, picnicking in the meadow by Azalea Woods, and a display of about 15 antique cars and Rolls-Royces on the Conservatory Lawn.
Field & Fête: Winterthur Celebrates 75 Years is scheduled for Saturday, May 16, 2026, from 10:00 a.m. to 4:00 p.m. on the breathtaking grounds of one of America’s great country estates. Tickets are $29; $15 for members. Rain date is May 17.
“In 1951, Henry Francis du Pont opened his extraordinary 175-room family home as a museum of American decorative arts, an act of remarkable generosity rooted in his belief that Winterthur’s beauty and history should inspire all who encountered it,” said Chris Strand, Charles F. Montgomery Director and CEO. “A true Renaissance man, ‘Harry’ pursued three great passions here: agriculture, horticulture, and collecting. He became an innovator and icon in all three.
“Today, his legacy continues through nearly 90,000 objects artfully displayed in the rooms where he once lived and entertained, gardens he considered his greatest canvas, and programs that carry his passion for learning and curiosity forward,” said Strand. “Field & Fête is our joyful tribute to that enduring vision and is an invitation to members and guests to experience everything he made possible.”
A Big Band, Parade, and Rolls-Royce Show
At the heart of the 75th anniversary garden party is the Unforgettable Big Band, a 20- piece ensemble with vocalists who will perform beneath a tent on Azalea Lawn from 11:00 a.m. to 3:00 p.m. The music sets the backdrop for the celebration, with a special performance by the BlueBallRoom Dance Studio swinging onto the floor at 12:30 p.m.
The band is scheduled to play four 15-song sets featuring a mix of popular songs that span the decades from the 1930s onward, with a large selection of music from the 1950s and ’60s, some ’70s and ’80s hits, and several contemporary titles. Styles include swing, ballad, waltz, pop, rock, Latin, and a few country songs.
Titles from 1951, the year Henry Francis du Pont (H.F.) opened his former house-turned museum to the public, include “Blue Moon,” “Blue Tango,” and “Unforgettable.” Other crowd-pleasing titles include Glen Miller’s “In the Mood;” Sinatra classics “Fly Me to the Moon,” “My Way” and “New York, New York;” “Boogie Woogie Bugle Boy” by the Andrews Sisters; and Aretha Franklin’s anthem, “Respect.” Modern crowd participation favorites “Sweet Caroline” and “Take Me Home, Country Roads” are also on the set list.
After the dance team’s performance, all eyes will turn to Garden Lane at 1:00 p.m. for the Chapters of Winterthur Parade, a charming 30-minute procession featuring one of Winterthur’s signature estate vehicles alongside gleaming vintage automobiles, stately Rolls-Royces, tractors, and the Delaware State Police Mounted Patrol.
Vintage Rolls-Royces and more will be lined up on the Conservatory Lawn from 10:00 a.m. to 4:00 p.m., showcasing the du Pont family’s passion for automotive excellence and luxury engineering. H.F. and his wife Ruth Wales du Pont owned more than 40 luxury vehicles during their lifetime, notably several Cadillacs and three Rolls-Royces, including a Phantom V.
Among the cars scheduled to be displayed by private collectors are a 1996 Bentley Brookland and 1956 Rolls-Royce Silver Wraith. Winterthur currently owns two Rolls Royces built in the United States, a 1927 dark green Phantom I Ascot Tourer and a 1927 burgundy Rolls-Royce Phantom I Pall Mall. These were donated to Winterthur and not owned by the du Ponts. The Ascot Tourer is scheduled to be in the parade and will be parked outside the Port Royal Entrance Hall.
Bring Your Own Picnic or Book a Private Tent
Guests can bring their own chairs and/or blankets and pack their own picnic or purchase food and beverages under the food tent. A limited number of 10-foot by 10-foot private picnic tents are available for rent, situated right in the center of the music and merriment. Guests in private tents, which include a 48-inch round table with linens, six chairs, and flowers, can opt for butler service.
Restaurant Associates, Winterthur’s on-site catering partner, brings an upscale grazing menu for purchase to the fields, including lobster bao buns, salmon rillettes, franks in a blanket, French-inspired charcuterie boxes, and truffle potato chips.
Winterthur’s culinary team will be on the grill serving Wagyu beef sliders, classic hot dogs, and hamburgers, alongside a skewer station featuring rhubarb miso-glazed shrimp, chicken with herbs de Provence and ramp chimichurri, along with tomato-marjoram glazed vegetables with halloumi cheese.
The frankfurters are a nod to the museum’s early days, when H.F. reportedly sold hot dogs to guests from the side porch of the Cottage, the 50-room English Regency-style residence designed by Thomas Waterman that H.F. and Ruth moved into in 1950, a year prior to the museum opening to the public.
For dessert, Field & Fête guests can savor chocolate strawberries layered with pistachios and shredded kataifi, beautifully presented in stemless wine glasses for strolling and savoring.
In addition, Woodside Creamery in Hockessin, Del., is crafting two small-batch, hand dipped ice cream treats for the event, available only at Winterthur. The Winterthur Swiss Avalanche flavor, originally created to commemorate the museum’s 50th anniversary in 2001, pays homage to both the origin of the estate’s name and its early days as an award-winning dairy farm. When H.F.’s ancestors Jacques Antoine and Evelina du Pont Bidermann settled the property in 1839 and built the original 12-room Greek Revival manor house, they named it Winterthur after the Swiss town where Jacques Antoine’s family originated.
Cows were a part of the Winterthur landscape since its earliest days. H.F. became farm manager in 1914, and in 1917, after much research and experimentation, he began breeding Holstein-Friesian cattle to improve the herd’s butterfat content.
Winterthur Swiss Avalanche ice cream is made from sweet cream and features mini chocolate cows made from Neuchatel chocolate. The moniker Neuchatel was taken from the Swiss city of Neuchatel, which is also known for its chocolates. Neuchatel chocolatier Albert A. Lauber V happens to have settled locally in Oxford, Pa. The limited-edition flavor will be featured at Winterthur throughout the year while supplies last.
The Winterthur Faeries flavor is a mint chocolate chip ice cream that Woodside Creamery originally created for May Day as an ode to Enchanted Woods children’s garden, which is celebrating its 25th anniversary this June. This limited-time special flavor features Swiss chocolate leaves and bugs mixed in with white chocolate toadstools. Vanilla ice cream with sprinkles and Rita’s Italian cherry water ice will also be available for purchase.
Toasts to Winterthur’s anniversary will be raised at the Sparkling Wine Bar. Options include Chandon Garden Spritz, Torresella Prosecco, and Chandon Sparkling Rosé, along with two signature cocktails, an Elderflower Spritz and H.F. du Pont 75. The latter is Winterthur’s version of the classic French 75, a popular cocktail in the 1950s that includes gin, lemon juice, and simple syrup combined in a shaker and topped with a splash of champagne.
Wilmington Brew Works, a local microbrewery with two taprooms in Wilmington, Del., has joined the celebration by issuing their Superfluous Nomenclature American pale ale with special-edition labels that honor Winterthur’s museum collection and 75 years of art, history, and nature. Featured are images of silver tankards made by Paul Revere on display in the museum’s Du Pont Dining Room; the sweeping, spiral Montmorenci staircase from North Carolina and installed in the family home-turned-museum; rare books from the Winterthur Library collection; and a photo of Winterthur’s daffodil drifts that have dazzled garden guests for more than 120 years.
Secret Spaces Tours — Limited Availability
Available only this weekend, the Secret Spaces Tour will take guests on a rare behind-the scenes journey through Winterthur’s hidden museum spaces, conservation areas, floral processing room, and more, concluding with a sparkling toast overlooking the Reflecting Pool. Limited tickets remain for 4:00 to 6:00 p.m. Friday, May 15, and Sunday, May 17. ($110; $100 for members. Includes Field & Fête admission on May 16.) Reservations required.
While The Court is a surprising delight seen on the More to Explore Tour, those on the Secret Spaces Tour will get to peek inside the Banister House and Montmorenci facades. Tourgoers will also get an insider view of the Flower Room and cold storage, which H.F. added during the 1928 expansion of the house. This was the main base of operations for former estate staffers who would follow his meticulous instructions for creating floral arrangements when the house was a home.
Textile and design lovers will get rare access to Winterthur’s Curtain Storage, which gives insight into H.F.’s design aesthetic and belief that textiles brought his collection and home to life. He developed detailed plans for changing elements like curtains and bedcovers for each season. This space houses curtains and valances that reflect the design tastes and history of textile collecting and use at Winterthur. See the work of Ernest LoNano, Winterthur’s upholsterer and curtain maker when the mansion was a family home.
Secret Spaces also includes a tour of Winterthur’s Needlework Storage, where guests will see exquisite examples of the textiles in the vast collection. These objects are often not on view due to the delicate nature of the fabrics, which are susceptible to light and other stressors.
