Originally built to protect the Virgin Islands from piracy, Fort Frederik (also called Frederiksfort) was the site of a different sort of historic stampede. In 1848, some 8,000 slaves marched through the streets of Frederiksted to this fort in order to demand their freedom. During your visit to this historical site, you can learn more about the emancipation rally and the "Triangle Trade," a slave ship route between Europe, Africa and St. Croix. Despite offering tons of information on these subjects, the fort is met with mixed reviews. One TripAdvisor reviewer suggests that the property is not living up to its potential, saying that "a visit to the museum inside rather disappointing, as there is so much more that could be done with it. I found it rather dreary."

You can tour Fort Frederik for an admission fee of $3 Monday through Friday from 8 a.m. to 4 p.m. and on Saturdays (when cruise ships are in port) from 8 a.m. to 3 p.m.
