What is fort armstrong hawaii?

Fort Armstrong was a United States Army coastal defense fortification on the island of Oahu, Hawaii. It was established in 1907 and was named after Brigadier General Samuel C. Armstrong, a Union Army officer during the American Civil War. The fort was part of a system of fortifications that were built to defend the harbor of Honolulu and the surrounding areas from potential naval attacks.

The fort was strategically located at the mouth of Honolulu Harbor, at the western end of Waikiki Beach. It was built on a 20-acre site that included a moat, a parade ground, barracks, officer quarters, and gun batteries. The fort had six 12-inch coastal defense guns that were mounted on concrete emplacements and could fire large shells over long distances.

In addition to its military functions, Fort Armstrong also served as a training facility for the Hawaiian National Guard and the Army Reserve. During World War II, the fort was used to house a signal corps detachment and a radar station.

After the war, the fort was used as a storage facility and later as a headquarters for the United States Army Corps of Engineers. In 1974, the fort was declared surplus and was transferred to the State of Hawaii.

Today, the site of Fort Armstrong is part of the larger Ala Moana Beach Park and is used for recreational activities such as jogging, picnicking, and swimming. The former gun batteries are open to the public for exploration and offer panoramic views of the beach and the surrounding areas.
