The Roosevelt Campobello International Park is a unique example of international cooperation. This 2800 acre park is a joint memorial by Canada and the United States and a symbol of the close relationship between the two countries. Here are the cottage and the grounds where President Roosevelt vacationed, the waters where he sailed, and the woods, bogs, and beaches where he tramped and relaxed. The Roosevelt Campobello International Park was established under an agreement signed by President Lyndon B. Johnson and Prime Minister Lester B. Pearson on January 22, 1964. The Roosevelt Campobello International Park was officially opened on August 20, 1964.
