The Lost World Aquarium, known until 2025 as The Lost Chambers, is Atlantis The Palm’s underwater adventure. Reopened in October 2025 after a major revamp, it takes you through 14 themed rooms inspired by the legend of Atlantis, home to around 65,000 sea creatures, from sharks and rays to a Giant Pacific Octopus. Catch the live mermaid show in the Ambassador Lagoon, and it makes a brilliant indoor half-day for families.
Now the Lost World Aquarium: What’s New
In August 2025, The Lost Chambers closed for a full makeover, and it reopened on 27 October 2025 as The Lost World Aquarium. The revamp added 14 themed rooms with 360-degree projection mapping, 1,900 LED panels and 140 speakers; 430 new animals across 35 new species; a live mermaid show; and an optional Interactive Trident that unlocks hidden effects as you explore.
The Story Behind the Experience
Rather than plain tanks, the aquarium tells the legend of the lost city of Atlantis. Exhibits are styled as ancient ruins reclaimed by the sea, so the visit feels like an adventure through a lost civilisation as much as a wildlife exhibit, which makes it especially memorable for children.
What’s Inside
The Lost World mixes real marine life with immersive storytelling. These are the highlights to look out for.
14 Themed Rooms
Each room has its own story, soundtrack and things to touch, brought to life with projections, lighting and sound.
The Ambassador Lagoon and Mermaid Show
Stand before the 10-metre-deep lagoon, where sharks and rays glide past the ruins and trained divers perform the live mermaid show.
New Species
Look out for the Giant Pacific Octopus, the axolotl and the striated frogfish, among 35 species new to the aquarium.
The Interactive Trident (Optional)
Carry the trident through the rooms to unlock more than 24 light, sound and digital effects.
