Prince Edward Island's oldest museum, The Garden of the Gulf, was established in Montague in 1958. It is housed in the former Montague Bridge Post Office and Customs House, an Island stone building dating back to 1888. Operated by a board of volunteers and staff, and supported by the Town of Montague, it is open to the public on a seasonal basis from June through September. The museum's collections and exhibits document and illustrate the history of Prince Edward Island, in particular the Three Rivers area of Kings County.

In the summer of 1986 the Garden of the Gulf Museum in Montague featured a summer exhibit "Memories of Montague". Interviews for the exhibit were conducted in April of 1986 by museum staff members Jean DeLory, Joanne Bieler, and Helen Gill. Those interviewed were long time residents of the Montague area.
