One of the original chain of Spanish missions, Mission San Fernando dates from 1797, and the rambling grounds include the original 1822 convento, with its 4ft-thick adobe walls and Roman arches showing construction of the time (and enclosing the only known remaining mission wine cellar). There's also a historical museum, replicated church and many gardens.
The gift shop sells saint-themed figurines and medallions, wrought-iron crosses and greeting cards.
