Often referred to as the 'second discoverer' of Cuba, German scientist, Alexander von Humboldt's huge Cuban legacy goes largely unnoticed by outsiders. This small museum displays a historical trajectory of his work collecting scientific and botanical data across the island in the early 1800s. Nearby is the Coche Mambí , an elaborate train carriage built in the US in 1900 and brought to Cuba in 1912. A palace on wheels, it once served as the Presidential Car.
