Cotta Fort, on the seafront beside Ozamiz cathedral, is the best-preserved Spanish-era fortification on the western coast of Mindanao and the standard postcard image of the province. The square coral-stone structure, with bastions at the corners and a small chapel inside, looks across the channel to Mukas and the mountains of Lanao del Norte.
The interior houses a shrine to the Virgin of the Immaculate Conception — patron of Ozamiz — and a series of statues of the apparitions of Mary. The walls can be climbed for a wide view of the bay; in the late afternoon the light on the white coral is particularly good. Entry is free.
