For three nights only, the normally daytime-only museum stays open until 9pm for light installations, live music and food

There’s something oddly thrilling about visting a museum after dark. Samut Prakan’s Naval Museum normally closes at 3pm on weekdays and doesn't open at all on public holidays. It’s a quiet, formal place built to preserve rather than perform.
That’s what makes Pai Kan Prakan (ไปกันปราการ) Eastern Flavour Fest so enticing. For three nights, the museum stays open until 9pm and takes on a completely different character after sunset.
Much of the appeal lies in the setting. At night, the seaplanes, submarine conning tower, tanks and guns scattered across the lawn look very different from how they do at 10am. Then there’s a replica of the Royal Barge procession staged with a light-and-sound show, plus LUMINA DREAM, a glowing installation shaped like a water droplet. Together, they turn the museum visit into a proper night out.
Inside, the permanent collection remains the heart of the museum. Founded in the 1940s, it traces Thailand’s naval history through uniforms, navigation instruments and weaponry once used by the Royal Thai Navy. There are also scale models of ships that have appeared in the Royal Barge procession since the reign of King Rama V. The standout is the preserved conning tower of HTMS Machanu, one of Thailand’s first four submarines and one of the rarest exhibits you’ll find in the country – worth building your visit around, event or no event.
Across all three evenings, concerts, performances and a good spread of food stalls add to the after-hours atmosphere. Entry is free, as it is during regular museum hours, and the latest event details are available through the Eventpass app.
