An important exhibit in the southern wing is one of the earliest images of the Buddha from Gandhara in India, clearly influenced by classical Greek sculpture.  A garage in a nearby building houses the collection of magnificent royal funeral chariots.  Vajayant Rajarot is still used even though it needs 300 men to pull it.
