Agusan del Norte sits at the gateway to the Caraga region on the northeastern coast of Mindanao. Its capital, Butuan City, is one of the oldest known settlements in the archipelago — a fact made remarkable by the gold artifacts discovered in its soil, which pushed Philippine history further back than anyone had previously established.
The Agusan River — the second longest in the Philippines — enters the sea near Butuan, carrying sediment from the vast interior watershed that the river has drained for millennia. It is this river that made Butuan rich in the pre-colonial period, connecting the highland gold sources of Mindanao with the maritime trade routes of Southeast Asia.
Archaeological discoveries in Butuan have unearthed gold jewelry, ritual objects, and trade goods dating to the 9th and 10th centuries — placing Butuan among the earliest documented trading polities in the Philippines. The balangay boats found buried near the city are among the oldest watercraft excavated anywhere in Southeast Asia.
