Among the beautiful beaches on the southern coast, Nilwella beach has a special place. It is because of a unique place that has attracted local and foreign tourists. The Navy and the Ministry of Fisheries have worked together to bring a new attraction to this coast, adding new energy to the country's tourism and the protection of the marine ecosystem as well as the country's economy. That beautiful creation is the beautiful museum built at the bottom of the Nilwella sea. Nilwella beach and island has been special for some time because of its beautiful beaches for diving activities that have attracted tourists from this country as well as foreign tourists. In order to enjoy the beauty of the beach as well as the beauty of the seabed, local and foreign tourists regularly dive in this sea area.
It is a special thing that this museum, which has been built at the bottom of the sea, has been created by the Navy using environmentally friendly materials, adding a brand new experience for local and foreign tourists. Various creative models including human figures, building models, vehicles including decommissioned buses, airplanes have been created in this. Substrates specially designed for coral growth are beautifully placed in this underwater art gallery. Some models here are designed by connecting small pieces of stone to each other, so it is believed that sea plants and corals will grow easily on those surfaces and an environment conducive to natural fish breeding will be created in a very short period of time.
