Sokehs has a prominent north-south ridge (known locally as "Pohndolap", overlooking the state capital Kolonia, and was fortified by the Japanese during World War II.

They built a road to the summit area and emplaced anti-aircraft guns on the ridge.

The ridge was also a key site in the 1910 Sokehs Rebellion against German rule, and the remnants of a Pohnpeian fort are also in the area.

The surviving elements of these fortifications were listed on the United States National Register of Historic Places in 1976.

[2] The old road is now part of a hiking trail, leading up to the fortifications.
