The George C. Boldt Yacht House, Church of Saint Lawrence, Cornwall Brothers' Store, Holland Library, Ingleside, and Longue Vue Island are listed on the National Register of Historic Places.

[2] The village is located on the south bank of the Saint Lawrence River near the U.S. and Canada international border.

NY-26 has its northern terminus at Alexandria Bay and leads southeast 11 miles (18 km) to Theresa.

According to the 2008-2012 American Community Survey, the total population of Alexandria Bay was 1,999 and 95.5% white.

[9] While Alexandria Bay has a relatively low population during the winter months and has no colleges, the late spring, summer, and early fall seasons bring an influx of vacationers and avid boaters that cause the population of the village to exceed 15,000.

Work was underway on the eleven buildings that would comprise the castle complex when in January 1904 Louise Boldt died, ending the dreams of a lifetime.

George Boldt ordered that all work be stopped and for 73 years the Castle and the other structures on the island were left to the forces of nature.

The Thousand Islands Bridge Authority acquired the property in 1977; since that time, several million dollars have been spent rehabilitating and restoring the castle and surrounding structures.

It is encouraged that attendees dress in pirate attire, as do the actors who line the streets.

The festival is also educational, with many groups providing galleries, displays, and informative presentations of the weapons and ships used during the Golden Age of Piracy.
