Stone and Brick

Stone is a material hewn from rock and is therefore part of the natural landscape. Brick, by contrast, is a man-made product. The use of brick dates back more than 6,000 years.

Granite is an igneous rock that is rich in quartz and feldspar. It is an important stone for building purposes because it is resistant to weathering and breaks into easily-used blocks. Furthermore it is an attractive material because of the sparkling quality of the stone. Two thirds of the county of Carlow is underlain by granite bed rock. For example the capstone of the Neolithic Browneshill dolmen is granite. Typically, in the nineteenth century granite was widely used throughout the county for a variety of building types. It can be found in a range of important public buildings such as Carlow Gaol and Carlow Courthouse but also in vernacular architecture, in estate cottages and simple gateposts and fences.

Brick is a small rectangular block of fire clay widely used in building construction. The use of bricks dated to over 6000 years ago. Bricks are held together with mortar, an adhesive usually made of cement, lime putty and sand in various proportions. The masonry must withstand loads and stresses in order to retain stability. Bricks are usually red in colour but variations in shade and colour are sometimes found. In the Carlow Railway Station designed by Sir John Mac Neill, yellow bricks were used in the major part of the construction. However granite is used throughout as a feature.
