Museum of the Revolution (Museo de la Revolucion)

in march 1957 the palace was the target of an unsuccessful assassination attempt against batista led by revolutionary student leader josé antonio echeverría. bullet holes from the failed attempt are still visible in the palacio's main stairway. the museum itself descends chronologically from the top floor starting with cuba's pre-columbian culture and extending to the present-day. the downstairs rooms have some interesting exhibits on the 1953 moncada attack and the life of che guevara. most of the labels are in english and spanish. in front of the building is a fragment of the former city wall, as well as an sau-100 tank used by castro during the 1961 battle of the bay of pigs. one hall is dedicated to the so-called special period.
