During the 1961 Bay of Pigs invasion, Fidel Castro had his headquarters in the former office of the sugar mill, but today the building is devoted to this revolutionary museum (closed for refurbishment at the time of research.) You can see the desk and phone from where Fidel commanded his forces, along with other associated memorabilia. Outside is the wreck of an invading aircraft shot down by Fidel's troops.
The concrete memorials lining the road to the Bahía de Cochinos mark the spots where defenders were killed in 1961. A more moving testimony to the Bay of Pigs episode is the Museo de Playa Girón.
