Adjectives in contemporary English almost never go after the noun. If they do, it's a deliberate inversion and is probably used for dramatic or poetic effect.
Examples:
The most prominent family in town was the family McCoy (norm. the McCoy family)
He languished 16 years in durance vile (meaning captivity, but this is an example of archaic and very purple prose).
Other elements of style can cause an adjective to follow a noun:
His thought processes were of a type bizarre and yet curiously logical.
Here what looks like a simple inversion is actually an example of ellipsis. The writer has dropped "that was" from between the noun and the adjective. To be utterly explicit (not necessary here), the sentence could have been written:
His thought processes were of a type that was bizarre and yet curiously logical.
When HamletHamlet's father's ghost speaks of "murder most foul" we can interpret this as an example of ellipsis or simply an archaic noun-adjective inversion.
Almost all instances of such inversions in contemporary speech and writing are throwbacks. Cf. "body politic" and so on.
