See The Rich History Of The Thousand Islands Region At These Museums & Historical Sites

Over the years New York's Thousand Islands region has served as a strategic military location for controlling multiple waterways, a playground for the ultra-rich, a center of Northern NY commerce and agriculture, and a haven for boating, fishing and outdoors enthusiasts. Its numerous historical attractions-from forts to museums to historic lighthouses-keep those traditions alive today.

Regardless of what brings you to the Thousand Islands, there are historical attractions sure to strike your particular fancy. Some rewarding spots to spend an educational day include:

Boldt Castle and Yacht House

1 Heart Island, Alexandria Bay

Boldt Castle on the St. Lawrence River

Construction began on Boldt Castle on Heart Island in 1900, at the bidding of millionaire hotel magnate George C. Boldt, as a tribute to his beloved wife, Louise. Designed as their summer dream home, it ultimately was not meant to be. Sadly, Mrs. Boldt passed away suddenly in 1904, just months before completion of the 120-room Rhineland-style castle. Mr. Boldt, who was inconsolable, immediately stopped construction, leaving the property vacant for 73 years, until the Thousand Islands Bridge Authority acquired it in 1977 and began a multimillion-dollar restoration. Nowadays, guests can enjoy a self-guided tour of the castle, yacht house, and surrounding grounds, as well as rent the historic property for weddings and special events.

Antique Boat Museum

750 Mary Street, Clayton, NY

Boats are pretty much essential in the Thousand Islands, so where better to have the Antique Boat Museum? North America's premier freshwater nautical museum features 300 unique, beautifully preserved boats, as well as thousands of recreational boating artifacts, on a sprawling 4.5-acre campus with 1,900 feet of dock space and 1,300 feet of shoreline on the St. Lawrence River. While there you can learn about boating history on the St. Lawrence River, row a St. Lawrence skiff in French Bay, tour George Boldt's 1904 106-foot houseboat and take a speedboat ride through the islands in a triple cockpit runabout. The museum also hosts special events throughout the season such as the 1000 Islands Concours D'Elegance, a classic car show.

Fort Ontario State Historic Site

Originally built by the British in 1755, Fort Ontario has been destroyed and rebuilt several times over the years. During its history, the fort changed hands between its English/Canadian founders and American neighbors during the American Revolution, War of 1812, and other conflicts. It was used by the U.S. military through World War II and served as a refugee camp for Holocaust survivors from 1944 to 1946 (the only one of its kind in the U.S.). In 1946, it was turned over to New York State, which began redeveloping the site in 1949, leading to the well-maintained historic site visitors experience today. Tour the fort's parade grounds, powder magazine, barracks, storehouse and officer's quarters to complete your voyage back in time. Check the fort's calendar for details on special events happening throughout the year.

Safe Haven Holocaust Refugee Shelter Museum

From August 1944 until February 1946, Fort Ontario in Oswego served as the only refugee camp for Holocaust survivors in the U.S. The Safe Haven Holocaust Refugee Shelter Museum tells the story of the nearly 1,000 World War II refugees from Europe-mainly Jewish expatriates, including concentration camp escapees-who were brought to the region as "guests" of President Franklin D. Roosevelt. Members of the camp who wished to remain in the U.S. after the war were able to, despite signing documents that stated otherwise when first arriving to the camp. The museum is open for tours from Memorial Day to Labor Day.

Sackets Harbor Battlefield State Historic Site

504 West Main Street, Sackets Harbor

When the War of 1812 broke out, Sackets Harbor Battlefield quickly became the center of American naval and military activity for the upper St. Lawrence Valley and Lake Ontario. The site also held a massive shipyard that once employed some 3,000 workers. Nowadays guests can tour the circa-1850 furnished Commandant's House and Navy Yard Grounds, and get a taste of early 19th century naval life amid the exhibit, On Board the Jefferson. Living history demonstrations are held Wednesday through Saturday from June through August; there's also a year-round interpretive trail, picnic pavilion and scenic views of Lake Ontario.

Built in 1801 at the headwaters of the North Branch of Sandy Creek, the Burrville Cider Mill is one of Jefferson County's oldest establishments and continues to welcome visitors who flock here for its coveted apple cider and freshly fried cider doughnuts. The building was originally used as a sawmill and a gristmill, harnessing a 30-foot waterfall to turn a turbine that powered the mill equipment. It was converted to a cider mill in the 1940s and now uses electricity to power its gear, but guests can still see the old penstock (a water tunnel) and stroll the decks overlooking the roaring falls.
