August 1628
You are a royal investigator tasked by Gustavus Adolphus to uncover the truth behind the Vasa's sinking in 1629 Stockholm.
You trace the disaster of this 69-meter war
Follow the trail of the royal ship Vasa through Stockholm, sunk in 1628 on its maiden voyage, and uncover the secrets of a naval disaster that shook the Swedish Empire.
Your investigation begins before Stockholm's Royal Palace, official residence of Swedish kings since 1754. Built between 1697 and 1754 by Nicodemus Tessin the Younger after the fire of Tre Kronor castle in 1697, this palace of 608 rooms on 7 floors witnessed Gustavus Adolphus's fatal decisions. Here the king ordered Vasa's construction in 1625, wanting to impress Europe with Swedish naval power. The royal guard still performs the changing ceremony daily at 12:15 and 1:30 PM since 1523, perpetuating a ritual born when Vasa was meant to protect these walls.
Your investigation leads to Riddarholmskyrkan, a Gothic church built around 1270 and royal mausoleum since 1632. In this 79-meter nave rests Gustavus Adolphus, died in 1632 at the Battle of Lützen, four years after Vasa's sinking. The tombs of 17 monarchs testify to the grandeur of a maritime empire broken by naval pride. The Chapel of the Knights of the Order of the Polar Star, created in 1748, honors those who tried to restore the royal navy's reputation after the 1628 catastrophe.
Strömbron bridge, rebuilt in 1875 in cast iron and granite, spans Norrström for 140 meters since the 17th century. From this viewpoint of the royal palace and Riddarholmen, Stockholmers helplessly witnessed the spectacle of Vasa capsizing before their eyes on August 10, 1628. The bridge's 18-meter width replaced the old wooden walkway from which courtiers watched this ship depart, meant to embody Swedish power, before it sank after 1,300 meters of navigation.
Kungsträdgården, transformed into royal gardens in 1637 by Queen Marie Eleonora, extends over 4 hectares where a medieval bastion of Tre Kronor castle once stood. This park, Stockholm's oldest public space, became the court's place of reflection after the Vasa catastrophe. The Kungsträdgårdsfontänen fountain, installed in 1866, indirectly commemorates this dark period when Sweden had to rethink its naval strategy. Here new, more stable ships were planned, learning from Vasa's failure.
Your journey ends at Skeppsholmen, an island fortified since 1626 that served as naval base until 1963. The Modern Art Museum installed in 1963 in a former 1828 naval building and the 92-meter royal yacht Af Chapman anchored since 1949 recall this site's maritime vocation. From this island accessible by bridge from Blasieholmen, you embark toward Djurgården to discover the Vasa Museum, opened in 1990. The ship salvaged in 1961 with its 700 sculptures and 95% original materials finally reveals its secrets: a lesson in humility carved in oak for eternity.
