Hidden beneath the monument is an air-conditioned museum containing many photos and personal belongings of Che and some of his comrades. Che's doctor's coat and olive green uniform, plus berets, pistols and rifles, knives, diaries, letters, radio, camera, fountain pen, asthma inhaler, medical and dentistry instruments are all carefully displayed.
The photos - some enlarged to nearly life-size - tell of his childhood in Argentina, the battles in the Sierra Maestra, the victory in this city of Santa Clara, and beyond to the struggle in Bolivia where he was killed on October 9, 1967.
