Flemish bond is a pattern of brickwork that is a common feature in Georgian architecture. The pattern features bricks laid lengthwise (stretchers) alternating with bricks laid with their shorter ends exposed (headers) within the same courses. This decorative pattern can be accented by glazing or burning the exposed ends of the headers so that they possess a dark, glassy surface that contrasts with the stretchers. Despite the bond's name, the pattern did not originate in Flanders and can be found in European architecture dating to the late Middle Ages.
