Visit the Capua Amphitheater where Spartacus made his mark as a Gladiator. Not as glamorous as the Roman Colosseum but it still stands. Rarely visited, you can wonder without crowds into the lower levels to see where preparations for battle were made. A must see for fans of Spartacus and his Slave Rebellion.
Slightly of the main walk - on the right when descending, you will find a rather huge pond with an island in the middle. It was built to provide military education, housing mock sea battles and entertainment - parties were thrown on the island.
but scarcely thought to look at it as other than the access to: - the garden, the waterfalls, the statues or indeed the staircase into the palace itself. The end view was pretty enticing really.
Now I forget, myself whether this was on the right or the left hand side of the grand hallway but it is there somewhere.
