[1] They are located well north of the main Allied landing areas of the 1944 Battle of Guam.

At the north end of the beach, about 25 metres (82 ft) inland from the high tide line, stands a gun emplacement with an attached pillbox.

The emplacement consists of two reinforced concrete walls flanking a Japanese 20 cm gun.

From this position a covered way leads to a badly damaged pillbox structure, also made of reinforced concrete.

It has a single opening, facing southwest, that is presumed to have acted as both access point and gun port.
