Singer Castle On

Dark Island

Was built in 1904 by Frederick G. Bourne.

Singer Castle at Dark Island: Was built in 1904 by Frederick G. Bourne.

It was formerly called “The Towers”. Mr. Bourne was a former Singer Sewing Machine executive. This summer home, built of granite quarried at the Oak Island stone quarry, cost $500,000. It is located on Dark Island about halfway between Alexandria Bay, NY and Brockville, Ontario, Canada, very near the Duck Cove Cottages.

In 1962, the castle was willed to LaSalle Military School, Oakdale Long Island, which is operated by the Brothers of the Christian Schools Order. Mrs. Alexander D. Thayer of Gwynett Valley, Pennsylvania, daughter of Mr. F.G. Bourne, deeded the property to the Brothers for one dollar due to a dispute over assessment of the island by the Town of Hammond. The building, on the 7 acre island, contains 42 rooms, with covered passage from the mansion to the boathouse and many underground passageways. For many years the island had its own power supply, but in 1969, a submarine cable was installed from Cedar to Dark Island. Next owners were Dr. and Mrs. Harold G. Martine, who operated non-denominational church services and retreats on the island. The present owners, an investment group from Germany have opened the castle to public tours. The castle can be accessed by your private boat or by tour boats out of Alexandria Bay, Morristown or Blind Bay.


Over 2,000 loads of topsoil were brought in to cover the eight acres of rock.

An American Tale
Tons of granite quarried from nearby Oak Island were brought over ice and water in 1902-1904 to construct Singer Castle (and at the same time Boldt Castle). Mr. Frederick Gilbert Bourne who resided at the Dakota Apartments, New York City was a self-made millionaire. The Bourne family had a 1,000-acre summer estate in Oakdale, Long Island. Mr. Bourne wanted to surprise his wife Emma and their children with an island ‘hunting’ retreat. He purchased Dark Island and had designed and built the castle originally known as "The Towers” for a cost of US $500,000. Italian stonecutters were engaged to shape the granite for the 4-story, 28-room castle, 4-story Tower, and an elaborate boathouse (one of three) which housed a workshop and powerhouse and one of Bourne’s steam-powered vessels, the tunnels, turrets and other curious architectural details including a 2-story ice house – essential for fine entertaining at the turn of the century, dungeons and underground passageways. Over 2,000 loads of topsoil were brought from Canada to cover the eight acres of rock.



Bourne’s summer neighbor on Ingleneuk Island, the famous American painter and sculptor Frederic Remington, wrote that he could hear construction work as the Castle was being built. Being a good neighbor, he sent a bouquet of flowers to his new neighbors upon completion.



American beaux-arts architect Ernest Flagg (1857 – 1947) designed the Castle after inspiration from Sir Walter Scott’s novel about Woodstock Castle (1832) in Scotland. A leading architect of his time, Flagg was busy with his other clients such as Andrew Mellon and had also completed two buildings for Bourne’s employer, the Singer Sewing Machine Co. One of these buildings was the Singer Tower which rose 47 stories tall and served as the tallest building in the nation for six months.

Frederick Gilbert Bourne was born on December 20, 1851, and while in his teens started working in the offices of Clark O.N.T. (Our New Thread) Company. (In the late 1800’s, George Clark developed the first thread that was suitable for use on sewing machines.) One night when hearing him sing, Clark invited him to perform for his business associates. In this way Bourne was introduced to the leaders in his field. Gradually Bourne worked his way up in the business to the head offices of the Singer Sewing Machine Company and became its Director and President at the young age of 36. Bourne also held the position of Commodore of the New York Yacht Club.



The Castle, originally called "The Towers", served as the perfect setting for entertaining Bourne’s contemporaries, personalities no less famous as Cornelius Vanderbilt and Vincent Astor. Bourne was fond of fast automobiles and speed boats and like to travel at a very fast pace. (He was once arrested for driving 25 mph in New York in his 1906 Mercedes!) He commissioned designs for a number of steam vessels, some of which can be seen at the Antique Boat Museum in Clayton. He was remembered as a keen businessman and very charitable to his community. He and wife Emma had 9 children. Bourne died in March, 1919.

What thrilling tales the castle could tell…
The marvels of the island and castle become apparent on arrival. Some of the highlights to see and experience:

– Jutting up behind the southern boathouse stands the now 5-story Clock Tower with four 6′ ft diameter clock faces. A local folklore is that they are made of solid gold! This functioning timepiece has Westminster Chimes that sound every 15 minutes.

– Singer Castle ‘s massive medieval entranceway with Knights of Armor standing guard beside the enormous marble fireplace. A marble stairway leads up to the former Breakfast Room where large Gothic windows frame the breathtaking views of the St. Lawrence River . Large ships pass in the Seaway almost close enough to touch.

– The walnut-paneled Library with many original books has a secret panel connecting to passages inside the walls. The Drawing Room features elk, caribou, deer and moose mounted on the four walls. A portrait on one of the walls tips back so the host can spy on his/her guests from the secret passageway. Grates for spying on guests are built into the walls!

– Experience the lifestyle of ‘yesteryear’ by viewing the interior furnishings such as Italian hand-carved ornate tables and chairs, wrought-iron chandelier, brass lamps, oak cabinets, bronze work, lithographs, paintings.


The Northern Boathouse built for a 100' steam yacht.

– Currently under renovation is the northern Boathouse with a slip 18′ by 125′ was built for the 100′ steam yacht. The boathouse also contains the original powerhouse with generator room, battery room, water and fire pumps and screw jacks to raise the yacht from the water for winter storage.
