Not actually a memorial to Señor Santamaría (Fidel's right-hand man at Moncada), but rather a small provincial museum quartered in former military barracks where Batista's troops surrendered to Che Guevara on January 1, 1959. Main displays are on natural history and on Cuban women throughout history.

The museum is on a hilltop at the north end of Esquerra across the Río Bélico. Look for the large cream-colored building behind the horse field.
