Himologan
Himologan was a fortified hill settlement above the Cagayan River in northern Mindanao. Its people cultivated the surrounding land and took shelter behind the heights overlooking the river. In the early seventeenth century the Recollect missionaries found a community led by Datu Salangsang here. Around 1626 they persuaded its inhabitants to move downstream, where a new settlement grew closer to the river mouth and the coast.
