Bismarck Archipelago

The Bismarck Archipelago is in Papua New Guinea, around the Bismarck Sea northeast of that country's main island.

It consists of three main islands and many smaller ones:
 * New Britain
 * New Ireland
 * Manus

The capitals are Rabaul, Kavieng and Lorengau, respectively. Rabaul has a population of about 20,000; the others are smaller.
