Shots were fired with 305mm Obuhov cannon (305/52 O) to honor Helsinki being capital of Finland for 200 years. The guns were retired from use in 1982, but one has been kept in shape for these special occasions. The gun was loaded with 80kg of gunpowder and 500l of seawater, leaving some 400m long trail of steam.
