A museum ship, or sometimes memorial ship, is a ship that has been preserved and converted into a museum open to the public, for educational or memorial purposes. Some are also used for training and recruitment purposes, a use found mostly with the small number of museum ships that are still operational, i.e., capable of regular movement.
Starting from my country

Best known museum ship of my country is the legendary
Georgios Averof (Greek: Θ/Κ Γεώργιος Αβέρωφ)

Georgios Averoff is the world's only surviving heavily armored cruiser of the early 20th century.Popularly known as a battleship but it is in fact an armored cruiser .
The vessel, belonging to the Pisa class, was being built at Orlando Shipyards at Livorno in Italy, when the Italian government cancelled the project due to budgetary concerns. The Greek government immediately stepped in and acquired the ship with a 1/3 down payment (ca. 300,000 gold pound sterling), paid with the help of a wealthy Greek benefactor, George Averoff, whose name she received.
During the Balkan Wars in 1912 and 1913, she was the Hellenic Navy fleet flagship during the campaigns in the North and Central Aegean islands, as well as the coastal cities of East Macedonia and Thrace.
Greece remained neutral during most of World War I. The Eleutherios Venizelos government in 1917 decided to participate on the Allies' side. At the end of the first World War in November 1918 she sailed to Constantinople and raised the Greek flag as one of the winning powers of the Great War. After, the signing of the peace treaties, Georgios Averoff with the rest of the fleet moved the Greek troops to Asia Minor.
She served on the Allied side during World War II, having fled to Egypt with the rest of the fleet. She led the Greek naval force when the fleet dropped anchor in the Faliron Bay, Athens on October 17, 1944, at the end of the Nazi occupation.
Georgios Averoff's last voyage was to Rhodes in May 1945, to commemorate the accession of Dodecanese from Italy. She was towed to her permanent berth in Faliron Bay in 1985, where is now open as a museum.
