"The World's Rarest Passport Unveiled"
The Sovereign Military Order of Malta, also known as the Knights of Malta, issues the world's rarest passport, with only around 500 diplomatic passports in circulation. Despite not having any land, the Order is a sovereign nation with its own constitution, UN observer status, and a rich history dating back nearly 1,000 years. Visitors to Malta can explore various sites related to the Order's history, including Fort St. Angelo, the National Library of Malta, and St John’s Co-Cathedral, where Caravaggio's famous painting is displayed.
