Honiara is the capital and the main harbour of Solomon Islands. Also, it is the administrative centre of Guadalcanal Province, located on the northern coast of the same-named island washed by the Pacific Ocean.

Its weight reaches 6860 tons and length exceeds 150 m. Diving depth reaches 55 meters. This giant lies just 12 km away from Honiara.
