Antongona

The archaeological site of Antongona is located in the Itasy Region of Madagascar (formerly Imamo), roughly 36 km west of Antananarivo and 6 km north of Imerintsiatosika, Itasy.

Antongona is a sacred hill, it consists of two royal houses dated from the 16th and 18th centuries AD, spaced roughly 300 m apart and a royal tomb. Situated on natural rock formations, stone walls and doorways augmented the inherent defensive qualities of the rock formations constructed upon.^[1] From the center of the structure, a full 360° view was obtained of the surrounding landscape, further exemplifying the defensive quality of the sites.

There is also a small museum that is open from 14h to 16h.^[2]

This site was added to the Tentative List of UNESCO World Heritage Sites in Madagascar on November 14, 1997, in the Cultural category.^[1]
