Introduction to the Duke's Memorial Hall: The Duke's Memorial Hall is the landmark building of Blenheim Palace, with a small tower and a bell tower on the roof. The four stone pillars supporting the gate of the Memorial Hall are called Corinthian pillars, which have the meaning of praising Marlborough's merits. The main body of the building is connected with stone columns, replacing walls. At the top of the memorial hall is a sculpture of a lion and a rooster fighting, symbolizing the power of victory.
