The 1812 constitution will go down in history as one of the most important moments and documents in the history of Spain, so it is understandable that Cádiz makes the most of it in modern cultural form. The museum covers every nook and cranny of that heady time, giving historical context to the movers and shakers that changed the fate of this country forever. The urban history of the city is also documented here, and it is curious how little has changed since the glory years of the 18th century.
