    The HMS Myrtle isn't just a hunk of metal on the seabed, it’s a portal to a very specific moment in history. We love that it's a real piece of the post-WWI Baltic scramble, a sloop sunk by a mine in 1919 while operating against Bolshevik forces. Dropping down to 33 metres, you immediately get a sense of its scale. At 81.7 metres long, the wreck is broken in two, but both sections are still impressive. We usually start our dive exploring the stern, where the gun mount is a clear reminder of its purpose. The triple-expansion engines, despite over a century underwater, are remarkably intact and make for a fascinating swim-through – just watch your buoyancy. The hold is also accessible, dark and silty, but worth a quick peek for the adventurous. Visibility here can vary, but on a good day, the light filtering through the broken hull sections is genuinely atmospheric. Despite the cold, the sheer sense of history makes it one of our favourites in the Baltic, particularly for those who appreciate wrecks with a story. Look for the small cod and blennies that have made this artificial reef their home; they add a splash of life to the steel.
