Parapet




Parapets are either plain, Embattled , perforated or panelled. The last two are found in all styles except the Romanesque .

  • Plain parapets are simply portions of the wall generally overhanging a little, with a Coping at the top and Corbel table below.

  • Embattled parapets are sometimes panelled, but oftener pierced for the discharge of Arrow s, etc.

  • Perforated parapets are pierced in various devices as Circle s, Trefoil s, Quatrefoil s and other designs so that the light is seen through.

  • Panelled parapets are those Ornament ed by a series of panels, either Oblong or square, and more or less enriched, but not perforated. These are common in the Decorated and Perpendicular periods.




PARAPET ROOFS


Parapets surrounding roofs are extremely common in London . This dates from the Building Act of 1707 which banned projecting wooden eaves in the cities of Westminster and London as they were considered a fire risk. Instead an 18-inch brick parapet was required, with the roof set behind. This was contined in many Georgian houses, as it gave the appearance of a flat roof which accorded with the desire for classical proportions.
