The Koh Chang Naval Battle Memorial sits in Laem Ngop subdistrict, Laem Ngop district, about 16 kilometres from Trat town and roughly 1 kilometre before Laem Ngop Pier. It's right on the route travellers already drive on their way to catch the Koh Chang ferry. The standout is the museum building itself, designed in the shape of a warship and facing out to sea, with a monument to Prince Chumphon (Krom Luang Chumphon Khet Udomsak), the founder of the modern Thai Navy, standing and gazing toward the waters where the battle took place.
What does this place commemorate?
The Battle of Koh Chang took place on the morning of 17 January 1941, a naval engagement between the Thai Navy and the French fleet (France under the Vichy government) during the Franco-Thai dispute over Indochina. The French force, led by the cruiser Lamotte-Picquet, attacked Thai ships anchored near Koh Chang. The Thai side lost HTMS Thonburi and several torpedo boats, along with sailors killed in the fighting. This memorial was built to honour the sailors who gave their lives and to keep this piece of history alive for later generations.
A little backstory
Every year around 17–21 January there's a commemoration of the Thai Navy's heroism in the Battle of Koh Chang, with a wreath-laying ceremony, merit-making, and exhibitions. Come during this window and the atmosphere is livelier than usual, but it's also a lot more crowded.

What is there to see?
The warship-shaped museum
The building itself is shaped like a warship. Inside, it tells the story of the Battle of Koh Chang, the life of Prince Chumphon, and displays related to the Thai Navy.
The Prince of Chumphon monument
A statue of the prince — affectionately known as "Sadet Tia" — standing and facing the sea. People stop to pay their respects before moving on, and it photographs beautifully in the late-afternoon light.
The Laem Ngop seafront plaza
An open garden and plaza by the water, with Koh Chang faintly visible in the distance. A relaxed spot to sit and catch the sea breeze.
Opening hours, entry fee, getting there
- Entry fee: The outdoor plaza, garden, and monument are free to visit. The museum itself opens during official government hours and may be closed at certain times, so set your expectations accordingly.
- Hours: The seafront plaza and garden are open to walk around at any time, while the museum opens during government hours, roughly midday. Come from late morning to afternoon and you're more likely to find it open.
- Location: Laem Ngop subdistrict, Laem Ngop district, Trat — about 1 km before Laem Ngop Pier and roughly 16 km from Trat town.
- Getting there: Drive from Trat town along the Trat–Laem Ngop road, about 25–30 minutes, or take a Laem Ngop songthaew and get off along the way before the pier.
- Time needed: Around 30–60 minutes to walk the grounds; allow 1–1.5 hours if you go into the museum too.
Timing trick
This place works better as a stop along the way than as a main destination. Slot it in just before or after your Koh Chang ferry to make the most of your time. If you're crossing on the morning ferry, a quick photo stop and then straight to the boat works just fine.
Who is this place for?
Honestly, this isn't a place you'd go out of your way for. But if you're into history, interested in naval stories, or just want a stop on the way to Koh Chang that mixes a bit of substance with a sea view, it does the job well. It suits families who want the kids to learn something, and anyone driving themselves who happens to pass by. If you're rushing to catch the boat for a pure beach trip, head over first and stop here on the way back.
