Introduction to the Red Flagship Battle Glory Memorial Square: The Red Flagship Battle Glory Memorial Square is located on the shore of the shipyard. During World War II, the Pacific Fleet fought desperate battles with German fascists at sea and on land. To commemorate the heroic sacrifice of the soldiers, an eternal flame is burning in the center of the square all year round. The main memorial is the C-56 Guards submarine, which was used during World War II. He was brave and skillful in fighting, sinking ten warships and severely damaging four, making great contributions.
