The Russalka Memorial was built in 1902 by Amandus Adamson in memorial to those who lost their lives at the Gulf of Finland on the Russian navy vessel called Russalka. The 16-metre sculpture was placed by the sea where the promenade from Kadriorg Palace comes down to meet the Bay of Tallinn. The monument depicts a bronze angel on a granite pillar pointing an Orthodox cross in the assumed direction of the sunken ship. https://www.visitestonia.com/en/the-russalka-memorial
