Ershawan Fort 二沙灣砲臺

3/26/2025

Ershawan Fort (aka Ershawan battery or Tenable Gate of the Sea 海門天險), is a Qing Dynasty era fort that once guarded Keelung Harbor among a network of other forts. For a brief time was taken over by the French during the Sino-French War. Now it stands as a wonderfully preserved monument to the past, with great views of Keelung Harbor.

Background:
Ershawan Fort started as a seaside fortification in 1840 as a response to the First Opium War. During the war, a British ship called the Nerbudda fired on the fort, destroying one of the soldier dorm rooms. The ship later bottomed out on a coral reef and the sailors were imprisoned.
In August of 1884, 5 French ships under direction of general S. N. J. Lespes attacked the forts at Keelung, attacking from the side. Because the cannons in Ershawan Fort could not rotate, they were useless against the ships. Most of the canons and gunpowder were destroyed or exploded. The next day the French Forces invaded Keelung with a force of about 500 men. They made a cemetery nearby for their men, which was later moved to Ershawan Fort were it still remains to this day.
After the war, in an effort to protect the coal reserves near Keelung from the French, the then Imperial Inspector on Military Affairs Liu Mingchuan decided to improve fortifications in Keelung by relocating the Ershawan fortress to the nearby hillside. The new fortress was built in western style with the help of German technicians. The new fortress was completed in 1888 and included two 6 inch Armstrong guns and one 8 inch Armstrong gun. Liu Mingchuan also installed new revolving bases for the cannons, and created a camp below with the "Tenable Gate of the Sea."
After the Japanese took Taiwan, the fort was barely used and fell into decay.
The fort was declared a national historic monument in 1997.
The fort and pathways were further restored in 2018.
Now it is a popular attraction in the area especially because of the great view of Keelung Harbor that can be seen from the fort.

Our Journey:

I have been to Ershawan twice believe it or not. The first time it was raining and windy and the trail to the fort was closed! So of course I had to come back.

See above for a video of the fort for a better look of the surrounding area.

On the way up to Ershawan Fort, you will come across many retired military related machines and weapons.

Like this giant propeller.

Or this rocket.

Or this ROC Jet.

Or this turret.

At the top of a hill is a large park which is a nice place to relax.

At the edge of the park you will find a trail that leads to the fort. When I first visited in 2018, the trail to the fort was under construction and fenced up. So we followed an alternated trail.

We followed the trail to the remnants of some other fortifications, which I thought were Dutch but now I am not so sure where they came from.
Anyway, the trail should not be under construction when you go.

"Ershawan Fortification"
"The history of Ershawan fortress can be traced back to 1840 during the Qing-British Opium War. At that time, the defense of Keelung had been moved from Sheliaodao to Ershawan and Sanshawan. Yao Ying, a Taiwanese commander and administrator, and Dahungga, a Taiwanese commander, were ordered to build eight fortresses near today's Fuxing Hall and Sansha. Durin the Qing-French War, the French fleet encroached and the fortress was destroyed by French naval guns. The French army landed to march into Taipei City. The first battle of the Qing-French War highlighted the strategic importance of Keelung's coastal defense and Taiwan. After the founding of Taiwan Province, Governor Liu Mingchuan hired German technician Boans to plan and design Western-style fortresses, including Ershwan fortress. The old Shawan Fort was built on the seashore with weak firepower and close range. The new Ershawan Fort was moved to the height of the hillside. It was built in 1886 and successfully deployed three new Armstrong guns purchased through Jardine Matheson (two 6 inch and one 8 inch), and completed in 1889. Among them, there are one 6-inch gun on the north side of the fort, facing the inner waters of Keelung Port; and two cannon bases, with the right fort equipped with 8-inch guns, the main fort, facing the primary entrance of Bachimen fishing port on the right side of Keelung."

Type/Feature: Western-style fort built in the late Qing Dynasty equipeed with three Armstrong breech guns (two 6-inch and one 8-inch).

"Keelung Harbor Layout"
"At the end of the Qing dynasty, the fortress at Ershawan, Dingshihge, and Xiandong formed a perfect firewall of defense. They worked together to defend Keelung Harbor."
There you go, two other forts you can visit!

"Well"
”With an inner diameter of 1.2m, and an outer diameter of 1.8m, the interior wall of the well was built with stones of random sizes. It was the main water source of the fort. According to the setting location of the well, it is assumed that the well's main function was not to provide drinking water, but to serve the military purpose of cooling down the cannons.

"Military Camp"
"The military camp is located on the Ershawan Heights, where the Ershawan army stationed. At present, the military barracks have been destroyed, leaving only the outer camp wall. The camp wall is stacked up in herringbone pattern and neatly and firmly stacked up in a simple yet strong structure."

"Cememetery"
"During the reign on Empower Guangxu, mostly soldiers from mainland China garrisoned in Taiwan. They were mostly buried here after death. They used to inscribe the name, place of origin, year of death, and name of the battalion, squad, and sentry etc. with their knives and swords."

View of the cemetery. Someone left there keys here a long time ago. It is typical in Taiwan to place lost keys in easy to find places in place the person that lost them comes back looking for them.
