Apia is the capital and largest city of Samoa, located on the island of Upolu. Samoa is often referred to as the 'Cradle of Polynesia' because its culture, known as 'Fa'a Samoa' (The Samoan Way), is considered one of the oldest and best-preserved in the region. Apia is famous as the final home of the Scottish author Robert Louis Stevenson (author of Treasure Island), who spent his last years here and is buried atop nearby Mount Vaea. His estate, Vailima, is now a museum and the residence of the Head of State. In 2011, Samoa made a significant geographical move by skipping a whole day (December 30th) to jump across the International Date Line. This was done to align its time zone with its main trading partners, Australia and New Zealand, moving from being 'the last to see the sun' to 'the first.'
