Phu Quoc Neptune Palace (also known as Kim Quy Aquarium or The Sea Shell) officially opened in 2022 and has been continuously upgraded by VinWonders, gradually becoming one of the prominent tourism symbols of Phu Quoc by 2026. The structure was designed by two of the world's leading architectural firms, Legacy GGE (USA) and AAT (Australia), inspired by the legend of the mythical city of Atlantis beneath the ocean floor, bringing a vivid and artistic ocean exploration experience.
A highlight of the structure is the main aquarium tank with a volume of up to 15,500 m³, along with a giant Acrylic glass panel measuring around 200 m², creating an impressive panoramic view that makes visitors feel like walking through the heart of the ocean and immersing themselves in the marine life world. The ecosystem here is extremely diverse with more than 255,000 marine creatures, including many rare species listed in the Red Book such as the Amazon Arapaima, Mekong Giant Catfish, or Giant Barb.
