Crown

The concrete cap at the very top of a masonry chimney.

What is Crown?

Not the metal chimney cap: the crown is the poured concrete or stone slab covering the top course of a masonry chimney, there to shed water away from the masonry below. Once it cracks, water enters the masonry and freeze-thaw spalling accelerates. Hairline cracks take a crown coat sealing; serious damage means a full rebuild.
