This ship might be one of the most famous battle ship in the world.
When the ship was built, it was the biggest, fastest and strongest.
On the deck, there are many canons.
It looks heavy.
How many soldiers had to treat the canons to aim enemies.
There are numerous canons in the ship.
The ship has steam engine.
To move coal, hanging rail is set on the roof.
It means navy soldiers carried lots of coal into the turbine.
To make it easy for tourists to walk around the battle ship,
they cut some walls even the ship is priceless legacy.
Inside the wall, steel rusts badly but it looks much better than I thought.
Because the outer shell of the ship works very well to shut out water.
Doors have racks and pinions on itself.
It must be heavy for human to move with manpower.
So I think the gates are moved with steam pressure.
