This underground museum tucked beneath Plaza de España tells a fascinating slice of history — it's home to the "Cañón Tigre", the actual cannon that fired the shot taking Horatio Nelson's right arm during the 1797 Battle of Santa Cruz. Small and easy to miss, but the story behind it is genuinely gripping. Free to enter, so there's no reason to skip it.
