wrack and ruin

Wrack and ruin describes a state of complete destruction or decay.

The phrase is emphatic and somewhat old-fashioned, typically appearing with verbs like go or fall: The old estate had gone to wrack and ruin after the family abandoned it.

Wrack here is an archaic word for destruction or wreckage, making the phrase essentially redundant—both words mean roughly the same thing—but the alliteration gives it staying power.
