The wreck of Thracia lies off the coast of France. The wreck was located after the war by a salvage company for scrap metal using explosives, destroying much of the ship.

One of the most distinctive features of the wreck is the two large boilers that lie side by side. Her Vickers machine gun is on display at the Musee de Quiberon.
