Gustaf Erikson once owned Åland, Finland and the world’s largest sailing ship company. The archive that was left behind provides a unique insight into our shipping history. The autonomous island province of Åland has received its first UNESCO heritage honour as the Gustaf Erikson’s shipping archives were included in UNESCO’s World Heritage Register, thus joining the same echelon of invaluable cultural heritage as England’s Magna Carta, the French Declaration of Human Rights, the Gutenberg Bible and Isaac Newton’s manuscripts.
