What is the main crown cornice

The main crown ledge, also called the gutter ledge, is an architectural feature that has the task of dividing the building wall from the under-roof. Usually this is the most decorative cornice on the house. The cornice is traditionally made up of a carrier component, supported by a component and a gutter plate. It does not only act decorative, it also acts as a protection of a building, a window or a door. The cornices have been an integral part of most of the houses for centuries, and the architectural styles of the twentieth century have begun to omit them.
