Finland

The wreck, which has been confirmed to be that of 300-year-old frigate Huis te Warmelo was found at a depth of 64 metres near Helsinki. The vessel was once part of the Dutch navy, specifically a region known as West Frisia. The ship was identified on the basis of hull dimensions, location, structure and armament.

Finland’s accomplished diver and wreck researcher Rauno Koivusaari, who discovered the famous treasure ship Vrouw Maria in 1999, has now also found the wreck of the Hanneke Wrome just south of the island of Jussarö in Finland. According to historic documents, the ship was carrying 10,000 gold coins, estimated to be worth around €50 million today.

The brew was reproduced thanks to elaborate research by Finnish and Belgian scientists who teamed up after the wreckage was discovered off Finland's Aaland Islands in 2010.

Divers exploring 40 feet down found only five bottles of beer next to 145 champagne bottles -- confirmed as the world's oldest drinkable bubbly -- in the long-lost wreck. The Government of the autonomous Åland Islands is the owner of the findings and had the beers analyzed at VTT Technical Research Center in Finland.

The 400-ton Russian submarine, commissioned in 1911, was the biggest in the pre-revolutionary Russian navy. During the first world war, she served in the Baltic Fleet making 16 patrols and unsuccessfully attacked the German coastal defence ship SMS Beowulf.

In November 1915 during her 17th patrol, she struck a mine and sank near Hiiumaa with the loss of all 35 seamen and came to rest at a depth of about 30 meters.

At the beginning of World War I the German submarine U-26 disappeared without a trace.

On October 11, 1914, she sank the Russian cruiser Pallada inflicting the first loss of the war on the Russian navy. The boat did not return from sea in August 1915 and is assumed to have struck a mine or suffered a technical failure off the coast of Finland.

The Finnish group of divers who goes by the name Badewanne states on their website:

A few bottles of beer were found in an old shipwreck in the archipelago of Åland in Finland during the summer of 2010. Researchers have now managed to isolate four different species of live lactic acid bacteria from the beer.

The 2010 discovery of the ship, believed to have sunk in the 1840s, also included the world's oldest champagne considered drinkable which has since been auctioned off.

The vessel rests at a depth of 80 meters and appears to be free of mud. According to some reports, it was carrying mixed cargo including steel products and as many as 1,000 bottles of cognac and 300 bottles of liqueur.

Raumanmeren Hylky-Team is a group of divers and wreck hunters who primarily search for shipwrecks in the Baltic sunk by German submarines during the First World War of which they have located around 20.

The divers say the vessel has remained quite intact. They will decide whether to try to raise the contents after closer examination.
