Japanese Coastal Defense Gun, World War II military site in Songsong, Northern Mariana Islands
The Model 3 coastal defense gun with 140-millimeter caliber sits within a concrete casemate measuring 7.7 meters wide and 6.6 meters deep.
The Japanese military constructed this strategic defense point in 1941 to guard the harbor against potential naval attacks during World War II.
This preserved military installation demonstrates the strategic importance of the Northern Mariana Islands during the Pacific theater operations of World War II.
The defense gun site occupies less than one acre on a cliff overlooking Rota's East Harbor, accessible through established walking paths from designated areas.
The reinforced concrete casemate incorporates specific design elements to merge with surrounding terrain while maintaining optimal defensive capabilities for artillery protection.
