Batanes Islands Project
Batanes Islands Project was an effort financed by the National Commission for Culture and the Arts. It explored the castle-like structures in elevated areas known as Ijangs. Also found in the site was an old settlement area known as Nakavajayan, as well as jar burials and boat-shaped markers. The stone boat-shaped burial markers were carbon dated and revealed to be from 1595 AD.
