A stepped gable, crow-stepped gable, or corbie step is a stairstep type of design at the top of the triangular gable-end of a building. The top of the parapet wall projects above the roofline and the top of the brick or stone wall is stacked in a step pattern above the roof as a decoration and as a convenient way to finish the brick courses. A stepped parapet may appear on building facades with or without gable ends, and even upon a false front.

Muchalls Castle stands overlooking the North Sea in the countryside of Kincardine and Mearns, Aberdeenshire, Scotland. The lower course is a well-preserved Romanesque, double-groined 13th-century tower house structure, built by the Frasers of Muchalls. Upon this structure, the 17th-century castle was begun by Alexander Burnett of Leys and completed by his son, Sir Thomas Burnett, 1st Baronet, in 1627. The Burnetts of Leys built the remaining four-storey present-day castle.
