A closer look
The battery sits on a knoll of volcanic rock at the harbour entrance, its gun positions cut into the basalt and lined with concrete, the surrounding vegetation having regrown enough to partially screen the emplacement from below while leaving the arc of fire across the channel completely clear, and the position gives a clear sense of how thoroughly the site was designed to cover every approach to the harbour.
Two large artillery casemates face the harbour mouth and the Pacific beyond, their steel doors hanging open, the barrels long removed but the mounting platforms intact, giving a clear sense of the scale of the guns that were once mounted here, and the interior of the casemates retains the original equipment alignment markings on the floor.
The interpretive panels at the site describe the night of December 1941 when the alarm was raised in Pago Pago following Pearl Harbor, and how the hastily reinforced harbour defences remained on high alert through the weeks when a Japanese naval attack was expected, a period that left the local population in a state of heightened tension that older residents still recall.
From the battery position the view down the harbour is wide enough to read the entire waterway at once, from the tuna cannery at the inner basin out to where the channel opens to the ocean, a vantage point that immediately communicates why this location was chosen for a coastal defence battery, and the sightlines remain as clear today as they were in 1942.
The concrete has weathered in the tropical air and the vegetation has sent roots into the cracks, creating the particular patina of a military historic site that is neither ruins nor properly maintained, sitting in a deliberate state of managed decay that preserves the physical evidence while allowing nature to reclaim the surfaces, a tension that is itself characteristic of American Samoa's approach to its WWII heritage.
Blunts Point is named for a British trading family who had a store near the harbour entrance in the 19th century, and the site has seen successive uses: German colonial period fortifications followed by the U.S. Naval administration that built the concrete battery that now defines the site, and the physical layering of these periods is still partially visible in the different construction styles visible in the concrete.
The battery is accessible via a short gravel track from the main coast road, with a small parking area at the trailhead and a moderately steep climb to the gun positions that takes approximately five minutes at a comfortable pace, and the approach through the overgrown vegetation gives no hint of the scale of the battery until the first casemate comes into view around the final bend.
It is the most physically intact World War II coastal defence site in American Samoa and one of the clearest examples of the Pacific theatre's impact on this territory.
The battery's position at the harbour entrance gives it a view that makes the tactical logic of the site immediately comprehensible to any visitor.
The site requires no climbing expertise and is one of the few easily accessible military history sites in American Samoa that combines physical remains with good interpretive signage.
Before you go
Current details checked July 2026
- Best season
- Accessible year-round; the dry season from May to October is most comfortable for walking the exposed site. The site can become overgrown during the wet season.
During the U.S. Naval administration period the battery was maintained; after the war it passed to the American Samoa government and the current interpretive infrastructure is modest.
