Command Ridge, Summit in Aiwo, Nauru

Command Ridge is the highest point on Nauru, rising about 65 meters above sea level. The ridge runs between the Aiwo and Buada districts and displays steep limestone cliffs with uneven, rocky terrain.

Japanese forces built their main communications center here during World War II, constructing extensive military fortifications across the summit. The ridge served as a key strategic position on the occupied island.

The limestone formations here hold meaning in local geography education, helping island children understand natural elevation. For residents, this ridge marks a physical landmark that divides two districts and shapes how they navigate their small island.

The ridge lies in Aiwo district near the Buada boundary, a short walk from the Buada lagoon side. No marked trail or facilities exist, so wear sturdy shoes and carry water; the coral surface is uneven and there is little shade.

Japanese inscriptions are still visible on bunker walls from the 1940s military occupation. Rusted artillery pieces remain scattered across the summit as physical reminders of that period.
