The Army Museum
It’s hard to imagine—in these tranquil, aloha-filled days—that the massive, reinforced concrete building on the shores of America’s most famous beach was once an active military fort. Constructed in 1911, it was fitted with high-powered guns that could hit targets more than 14 miles away (not too shabby for a century ago!) meant to defend Honolulu Harbor from invasion. The fort now shares historical facts ranging from the origins of the Hawaiian Islands to details of the attack on Pearl Harbor, which you can learn about on one of the audio tours. A majority of the staff are retired Army members, including family members of the men who served at this fort.
