Boldt Castle
Boldt Castle is a major landmark and tourist attraction in the Thousand Islands region of the U.S. state of New York. Open to guests seasonally between mid-May and mid-October, it is located on Heart Island in the Saint Lawrence River. Heart Island is part of the Town of Alexandria, in Jefferson County. Originally a private mansion built by American millionaire George Boldt, it is now maintained by the Thousand Islands Bridge Authority as a tourist attraction. History. George Boldt, general manager of the Waldorf-Astoria Hotel in New York City and manager of the Bellevue-Stratford  Hotel in Philadelphia, and his family enjoyed an earlier frame cottage on Hart Island (the island's original name) for several summers, which they greatly expanded. In 1900, George Boldt launched an ambitious construction campaign to build a huge masonry structure, one of the largest private homes in the United States. He engaged the architectural firm G. W. & W. D. Hewitt and hundreds of workers for a six-story "castle" as a present to his wife. In addition, four other masonry structures on the island are architecturally notable. Equally distinctive is a huge yacht house on neighboring Wellesley Island, where  the Boldts had another summer home and a vast estate, incorporating farms, canals, a golf course, tennis courts, stables, and a polo field. The construction of Boldt Castle ceased abruptly in early 1904 after the death of Boldt's wife, Louise Kehrer Boldt. Boldt never returned to Heart Island, but continued to spend summers in the 1000 Islands until his 1916 death. For 73 years, the castle and other stone structures were left exposed to the harsh winter weather and occasional vandals. The Thousand Islands Bridge Authority acquired Heart Island and the nearby yacht house in 1977, for one dollar , under the agreement that all revenues obtained from the castle operation would be applied towards restoration, so that the island would be preserved for the enjoyment of future generations. In the two decades after acquiring the property, the Thousand Islands Bridge Authority spent around $15 million for restoration and improvements with work continuing annually. The initial goal of the restoration of Heart Island was not to finish what had not been completed, but to restore the island to the state it was in when construction was halted. Improvements have surpassed that goal, as a stained glass dome, marble floor , grand staircase woodwork, butler's pantry, maid's and servant's dining rooms and kitchen were restored. As of 2020, over $50 million has been spent on restoration and rehabilitation work on the Castle and surrounding structures. Current estate. Today, Boldt Castle is accessible by ferry, private boat, or by tour boat from Alexandria Bay, New York, Clayton, New York, Gananoque, Ontario, Rockport, Ontario, and Ivy Lea, Ontario. Most of the grounds and buildings can be explored by the public for a fee. Private boaters may also dock at Heart Island for free. Boldt Castle is a Port of  Entry and has a U.S. Customs and Border Protection office on Heart Island. Visitors coming from Canada require appropriate identification to check in to the country, as visiting the island is considered entering the United States. The Power House is located on the eastern edge of the island and was built to hold a generator to supply the island with power via steam generator. Exhibits inside describe how power was obtained in the early 1900s and hosts a small display of historic photographs of Boldt Castle construction and the 1000 Islands region Nearly destroyed by a fire in the 1930s , the Power House was one of the first restoration projects completed after the Thousand Island Bridge Authority acquired it in 1977. Alster Tower was modeled after a Rhineland defense tower in Germany and purposely constructed with slanting and uneven walls, ceilings, and roofs. This unique structure sits on the south side of the island facing Alexandria Bay and boasts a two-lane bowling alley and stage for performances. The Alster Tower cafe is one of the restoration projects currently taking place on the island. The George C. Boldt Yacht House on nearby Wellesley Island represents the only remaining wooden yacht  house structure of this kind. The interior features extensive living quarters and a number of antique and wooden boats. For an additional admission fee, visitors can take a shuttle from Heart Island to the Yacht House on Wellesley Island to tour these exhibits. It was listed on the National Register of Historic Places in 1978. The 1969 children's novel "Secret Castle" by Anne Colver is about the castle and Alexandria Bay.
