In 1731, Gothenburg became the epicenter of the Swedish East India Company, launching secret voyages to China laden with riches and rivalries
You are a confidential agent of Gustav II Adolf, dispatched to Gothenburg in 1637 to safeguard the nascent port's future.
Your mission: thwart a conspiracy aiming to divert its wealth. You
Delve into the maritime and royal intrigues of Gothenburg, where the secrets of the Swedish East India Company still lie dormant beneath the cobblestones of Västra Götaland.
Your quest begins in Gustaf Adolfs Torg, Gothenburg's central square, founded in 1619 by King Gustav II Adolf. In front of the 5.5m equestrian statue, sculpted by Bengt Erland Fogelberg and inaugurated in 1854, you examine the city's coat of arms, searching for hidden clues in its symbols. This location, the historic administrative center with the city hall built in 1758, was the scene of royal speeches in the 17th century, key moments for the Kingdom of Sweden. As a royal envoy, you must decipher the first signs of the conspiracy threatening Sweden's commercial interests in Västra Götaland.
Continuing your visit to Gothenburg, you reach the Ostindiska huset, a neoclassical building from 1754, headquarters of the Swedish East India Company. Designed by architect Bengt Wilhelm Carlberg, this 1,200 m² edifice was the starting point for the first expedition to China in 1732. Today a museum, it houses Chinese porcelain trade artifacts. You search for messages hidden in cargo manifests, imagining the visits of Chinese diplomats in 1843. This listed Monument in Sweden, a testament to global trade, is a crucial step in understanding the economic stakes of the conspiracy.
The route then takes you to Packhuskajen, Gothenburg's historic port quay, built in the 1760s for naval storage. This location is an essential part of the Gothenburg canal, dug between 1642-1643 by order of Christopher IX. The old warehouses, the 18th-century packhus, were connected to Kronhuset, another major site of your exploration. Today a pedestrian area offering views of the nearby Feskekôrka canal, the quay retains the echo of merchant ships. Here, you decipher maritime signals, tracing suspicious movements of ships carrying illicit goods.
Your investigation leads you to Kronhuset, the royal warehouse completed in 1670 by architect Nicodemus Tessin the Elder. It was Gothenburg's largest building in the 17th century, capable of storing 20,000 tons of grain. It was used to supply the royal fleet during the Scanian War (1675-1679). The inner courtyard, with its 1660 well, is an ideal place for a secret rendezvous. You examine ancient graffiti and carpenter's marks, looking for symbols that could reveal the conspirators' identity. This historical heritage site in Västra Götaland is an essential link in Gothenburg's history.
Concluding your Västra Götaland thematic circuit, you have gathered the evidence and unmasked the culprits. From Gustaf Adolfs Torg to Ostindiska huset, via Packhuskajen and Kronhuset, each historical site in Gothenburg has revealed a piece of the puzzle. This interactive visit to Gothenburg will have plunged you into the heart of 17th-century political and commercial maneuvers. The gardens of Trädgårdsföreningen, Skansen Lejonet fort, Feskekôrka market, and Röhsska museet, while not directly linked to the 17th-century plot, bear witness to the city's evolution, from its military past to its current cultural richness. You take with you a deep understanding of Gothenburg's history and its strategic role in the Kingdom of Sweden, a true GPS treasure hunt through the monuments of Västra Götaland.
