Caracol Museum/Gallery of History (Museo de Caracol/Galería de Historia) is within Chapultepec Park, about halfway up the hill to Chapultepec Castle. The name “caracol” refers to the building's spiral shape, which resembles a snail's shell.
Twelve descending salas (exhibit halls) offer detailed, colorful dioramas that depict memorable past events in Mexican history, including Father Miguel Hidalgo's military campaign to secure independence from Spain, the Mexican-American War, French intervention in the 1860s and the Mexican Revolution of 1910. The chamber of red tezontle (volcanic) stone at the end of this walk through the past is covered with an impressive dome and is dominated by three objects: the national flag, a carved-stone eagle and a facsimile of the 1917 Constitution. Explanations are in Spanish.
