Finnish National Museum investigates mysterious shipwreck near Suomenlinna archipelago

The Finnish National Museum is investigating a mysterious shipwreck located near the historic Suomenlinna archipelago. Known as “Hilma,” this wooden vessel measures approximately 33 meters in length and 8 meters in width. Its original name and origin remain unknown. Formally designated as Wreck of West Mustasaari 2, the shipwreck lies east of West Mustasaari and is easily accessible from land.

Preliminary estimates suggest that the Hilma sank around 1780, with timber identified as originating from the northern Baltic Sea coast. The investigation has been ongoing for three years, led by a team of maritime archaeologists.

Early interpretations indicate that the wreck may have been intentionally sunk, as large stones found within the hull suggest this possibility. Maritime archaeologist Minna Koivikko expressed that once the wreck’s dating and structural details are determined, they will explore archival sources to uncover its history and reasons for its specific location in shallow waters. The wreck represents a common type of wooden ship from the Suomenlinna area, characterized by the preservation of its hull while remaining partially intact with loose structural components.

Due to its location, the wreck has been constantly affected by human activity, and its examination is part of a six-year research project led by Stockholm University titled “Forgotten Fleet.” The Finnish National Museum will continue to participate in this project for another three years.

In addition to examining the wreck, the research team includes an expert in photogrammetry who is tasked with creating a 3D model of the Hilma, facilitating virtual exploration of the wreck using virtual reality tools.
