Thousand Islands Bridge
The Thousand Islands International Bridge is a system of bridges maintained by the United States that crosses the Saint Lawrence River. It links northern New York with southeastern Ontario, Canada. The original structure was built in 1937, with expansions added in 1959. The bridge spans the Canada–US border through the Thousand Islands region.
Boldt Castle and the Boldt Yacht House
Construction began on Boldt Castle in 1900 as a summer home commissioned by millionaire hotelier George C. Boldt for his wife Louise. The castle was designed to rival those of Europe and is located on Heart Island in the St. Lawrence River, in the center of the 1000 Islands. Construction halted suddenly when Mrs. Boldt died months before its completion, and the property remained vacant for over seventy years.
1000 Islands Tower
The 1000 Islands Tower is a concrete observation tower built in 1965 located on Hill Island in Ontario near the U.S.-Canada border. It rises 400 feet (120 meters) above the St. Lawrence River and offers views over the Thousand Islands of both Canada and the United States.
Zavikon Island Bridge
Zavikon Island features a 32-foot-long bridge that connects a Canadian island to an American island, making it the shortest international bridge in the world. According to the border agreement between Canada and the United States, no island can be divided between the two countries. Approximately two-thirds of the islands belong to Canada, but their total land area is about equal to the American islands, which make up one-third of the group.
