Former Finnish Prime Minister Paavo Lipponen has made a significant contribution to the Finnish Maritime Museum by donating a rare collection of six books known as the Portugaliae Monumenta Cartographica. These books, which include historical maritime maps and research relating to the Age of Discovery from the 1400s to 1600s, were given to Lipponen as a gift from the Portuguese government. The donation is particularly notable as it celebrates the 500th anniversary of the death of Prince Henry the Navigator, an important figure in the history of maritime exploration.

The Portugaliae Monumenta Cartographica series, published in 1960, is described by the museum as a unique and rare collection, emphasizing its significance in both historical and academic contexts. These works were originally gifted to heads of state attending an EU summit during Portugal's presidency in the year 2000, showcasing the importance of international cooperation in the field of cultural heritage. The donation will enrich the museum's collection, allowing it to preserve and showcase these important documents related to Portuguese maritime history.

The Finnish Maritime Museum will incorporate this collection into its archival resources in Kotka, making it accessible not only to supporters of the museum but also to the general public. This act of philanthropy by Lipponen underscores the value of preserving historical artifacts and promoting awareness of maritime exploration's impact on global history, and it serves as an important reminder of Finland's connections through its maritime pursuits.
