Mouldering

The wood was kindled, the flames arose, and a mouldering heap of ashes was soon all that remained of Mrs Askew and her fellow martyrs.

I saw the mouldering ruin of an abbey overrun with ivy, and the taper spire of a village church rising from the brow of a neighboring hill.

Several heavy stones were hurled from the mouldering battlements into the roaring sea beneath.

You are a mouldering wreck.
