Kalanay Cave

The Kalanay Cave is a small cave located on the island of Masbate in the central Philippines. The cave is located specifically at the northwest coast of the island within the municipality of Aroroy. The artifacts recovered from the site were similar to those found to the Sa Huynh culture of Southern Vietnam. The site is part of the "Sa Huynh-Kalanay Interaction Sphere" which was an Iron Age maritime trading network associated with the Austronesian peoples of the Philippines, Vietnam, Taiwan, as well as most of northeastern Borneo and Southern Thailand.

The type of pottery found in the site were dated 400 BC to AD 1500. The "Sa Huynh-Kalanay Interaction Sphere" is characterized by a remarkable continuity in trade goods, including decorated pottery and double-headed pendants and earrings known as lingling-o.
