Fishbourne Roman Palace was built in the 1st century for Cogidubnus, the local king who co-operated with the Romans. It is the largest Roman residence North of the Alps.
It was destroyed by fire in the 3rd century.
The palace was discovered in 1960, and is now in the care of English Heritage, and open to the public.
A garden has been planted with the herbs and plants that would have been grown in the Roman period.
