Fodor's Expert Review Fuerte de Niebla

To protect the all-important city of Valdivia, the Spanish constructed a series of strategic fortresses at Niebla, where the Valdivia and Tornagaleones rivers meet. Portions of the 1671 Fuerte de Niebla and its 18 cannons have been restored. The ground on which the cannons sit is unstable; you can view them from the ramparts above. The old commander's house serves as a small museum documenting the era's military history.
