Nimoa Island - here the island mission will impress. The five-sided church features murals of island life and all mission buildings are surrounded by well maintained paths and gardens filled with flowering plants. Edged by jungle-covered mountains, postcard beaches and crystal clear waters - an island paradise indeed! The Louisiade Archipelago is a string of ten larger volcanic islands frequently fringed by coral reefs, and 90 smaller coral islands located 200 km southeast of New Guinea, stretching over more than 160 km and spread over an ocean area of 26,000 km? between the Solomon Sea to the north and the Coral Sea to the south. The aggregate land area of the islands is about 1,790 km? (690 square miles), with Vanatinai (formerly Sudest or Tagula as named by European claimants on Western maps) being the largest. Sideia Island and Basilaki Island lie closest to New Guinea, while Misima, Vanatinai, and Rossel islands lie further east. The archipelago is divided into the Local Level Government (LLG) areas Loui!
