Quoins are decorative stones at the corners of brick or stone buildings. Sometimes they are made of bricks on a stone building, or of contrasting coloured bricks on a brick building. In older buildings quoins were structural, and added strength at the corners. In more recent buildings, quoins are decorative, and are added to make a building look stronger, or simply give it an 'older' style look. Quoins on a house that is made from timber or any other light building material are purely decorative.
