Perched 177 meters above the sea, Cannon Fort is one of the most rewarding viewpoints on Cat Ba Island — part military relic, part panoramic lookout. If you're mapping out your time as part of the wider Cat Ba Island Travel Guide, this fort deserves a slot on your list, especially around sunset.
Where is Cannon Fort on Cat Ba island
Cannon Fort sits at 239 Cai Beo Street in Cat Ba town, about 3km from the town center. A taxi or motorbike gets you there in a few minutes.
Also known as Entrenched Fortification 177, the site includes tunnels, military trenches, and two large anti-marine cannons left over from the 1940s. Its position facing the sea on three sides gave Vietnamese troops a major tactical advantage during past conflicts, and today gives visitors a clear view out over the East Sea.
Coming here, you get both a scenic overlook of the bay's limestone mountains and a firsthand look at the historical memorabilia from Vietnam's wartime past.
Famous historical relics inside Cannon Fort
Cannon Fort holds several relics dating back to the 1940s, including an observatory, a bunker, a traditional room, and a love room.
Anti-sea cannons
The two large anti-sea cannons, each weighing tens of tons, are the fort's most eye-catching feature and the reason most visitors come.
Observatory
Set at the fort's highest point, the observatory offers the best vantage point for admiring Cat Ba's natural beauty from above.
Bunker
During wartime, the bunker sheltered revolutionary soldiers. It now functions like a miniature history museum, displaying military weapons of historical significance.
Traditional room
This room keeps memorabilia from the island's wartime struggles — weapons, models, guns, and photographs.
Love room
Named for being the place where soldiers reunited with loved ones after long separations, the love room also served to boost morale among the troops.
U-shaped tunnel
This atomic bomb-proof bunker has a high-dome structure and could accommodate up to 500 people. It's very dark inside, so bring a flashlight if you plan to explore it.
