Step into History: Exploring the Timeless Beauty of Boldt Castle

Originally conceived as a private mansion and a testament to love, Boldt Castle was commissioned by the American millionaire, George Boldt. With its regal turrets and intricate stonework, the castle embodies the vision of a man whose affluence and passion were matched only by his unyielding devotion to his wife.

Today, the Thousand Islands Bridge Authority meticulously maintains Boldt Castle as a tourist attraction. Visitors from near and far are invited to explore its grand halls, lush gardens, and hidden nooks, each filled with the echoes of a love story that transcends time. As the castle continues to captivate and inspire, it remains a cherished symbol of the Thousand Islands region’s rich history.

Building a Dream: The Extraordinary Construction of Boldt Castle

George Boldt, the general manager of the Waldorf-Astoria Hotel in New York City and Bellevue-Stratford Hotel in Philadelphia, along with his family, spent their summers at their expansive, charming frame cottage on Hart Island, the island’s original name. In the early 1900s, George Boldt embarked on an awe-inspiring construction endeavor to create one of the largest private homes in the United States – a monumental, six-story masonry castle that would stand as a testament to his devotion to his wife.

The esteemed architectural firm G. W. & W. D. Hewitt was enlisted for the construction of his vision, and hundreds of laborers set to work. Boldt Castle was accompanied by four other remarkable masonry structures on the island, each an architectural marvel. The opulence extended to neighboring Wellesley Island, where the Boldts owned a vast estate complete with another summer home, farms, canals, a golf course, tennis courts, stables, and a polo field. A large yacht house, a testament to the Boldts’ lavish lifestyle, also adorned the island.

Love, Loss, and Abandonment

However, tragedy struck in early 1904 with the untimely death of Boldt’s beloved wife, Louise Kehrer Boldt. Heartbroken, Boldt ceased construction of the castle and never returned to Heart Island, though he continued to spend summers in the Thousand Islands region until his death in 1916. For 73 years, Boldt Castle and the other magnificent stone structures lay abandoned, exposed to the ravages of harsh winter weather and the destruction of occasional vandals.

Preserving the Past

In 1977, the Thousand Islands Bridge Authority acquired Heart Island and the nearby yacht house for just one dollar. The agreement stipulated that all revenue generated from the castle’s operation would be directed towards restoration, preserving the island for future generations to cherish. Boldt Castle made its debut in 1979, serving as a backdrop for the movie Fear No Evil.

Over the next five decades, the Thousand Islands Bridge Authority invested nearly $15 million in restoration and improvements, with work continuing annually. While the initial goal was to restore the island to its state at the time of construction’s halt, ongoing enhancements have surpassed that aim. The castle now boasts a restored stained glass dome, a marble floor, intricate grand staircase woodwork, a butler’s pantry, and opulent maid’s and servant’s dining rooms, as well as a fully restored kitchen. As of 2023, over $50 million has been dedicated to the meticulous restoration and rehabilitation of Boldt Castle and its surrounding structures, ensuring that the extraordinary structures continues to captivate the hearts and imaginations of visitors for generations to come.

A Gateway to Grandeur

Today, Boldt Castle welcomes visitors to embark on a journey across the tranquil waters of the Saint Lawrence River, accessible by ferry, private vessel, or one of the many tour boats operating from Alexandria Bay, New York, Clayton, New York, Gananoque, Ontario, Rockport, Ontario, and Ivy Lea, Ontario. A sense of wonder and anticipation fills the air as guests set foot on Heart Island, ready to explore the grandeur of the grounds and buildings.

Private boaters are granted the privilege of docking at Heart Island free of charge, while Boldt Castle further serves as a Port of Entry, complete with a U.S. Customs and Border Protection office on the island. Canadian visitors must present appropriate identification, as setting foot on Heart Island is considered entering the United States.

Step into Elegance: Exploring the Rooms of Boldt Castle

The meticulously restored and beautifully furnished rooms on the first and second floors of Boldt Castle provide a wonderful atmosphere for guests. The second floor is home to the gift store, where visitors can purchase souvenirs, as well as a theatre that showcases a 16-minute introductory video delving into the life of George Boldt and the remarkable history of Boldt Castle.

While the third and fourth floors remain largely unfurnished, they house interesting exhibits featuring photographs and original artifacts from the Gilded Age, offering visitors a glimpse into the Boldts’ lavish lifestyle in the Thousand Islands region. Several rooms have been intentionally left unfurnished, inviting guests to imagine the castle’s appearance prior to the restoration efforts undertaken by the Thousand Islands Bridge Authority.

Boldt Castle’s basement remains largely unfinished, featuring a pool, numerous compartments, and a tunnel passage leading to the Power House. At the edge of the island, an imposing peristyle archway stands, envisioned as the original entrance for boats to Heart Island. The bridge connecting the two sides would have been designed to be raised and lowered as needed, further accentuating the castle’s unique design.

The Many Other Structures on Heart Island

Situated on the eastern edge of Heart Island, the Power House stands as a testament to early 20th-century ingenuity. This building was specifically designed to house a generator capable of supplying the entire island with power through a steam generation system. Exhibits within the Power House provide a fascinating insight into how electricity was harnessed in the early 1900s, while also showcasing a display of historic photographs depicting the construction of Boldt Castle and the surrounding Thousand Islands region. Though nearly destroyed by a devastating fire in the 1930s, the Power House was one of the first restoration projects undertaken by the Thousand Islands Bridge Authority after acquiring the property in 1977.

Drawing inspiration from a Rhineland defense tower in Germany, the Alster Tower was purposefully crafted with slanting and uneven walls, ceilings, and roofs, lending it a striking, one-of-a-kind appearance. Situated on the island’s southern side, overlooking Alexandria Bay, this architectural marvel houses a two-lane bowling alley and a stage for performances.

On nearby Wellesley Island, the George C. Boldt Yacht House stands proudly as the sole remaining wooden yacht house structure of its kind. The interior boasts lavish living quarters and an impressive collection of antique and wooden boats. For an additional admission fee, visitors can journey via shuttle from Heart Island to the Yacht House on Wellesley Island to see these exhibits. In recognition of its historical significance, the Yacht House was listed on the National Register of Historic Places in 1978.

The allure of Boldt Castle and the charm of Alexandria Bay have not gone unnoticed in popular culture. The 1969 children’s novel “Secret Castle” by Anne Colver masterfully weaves a tale centered around the enchanting castle and the picturesque bay, capturing the imagination of readers of all ages.
