Rubble/field stone masonry is composed of uncoursed rounded field stones or roughly-cut stones used for construction with or without mortar. There are two wall wythes and a core, usually filled with stone rubble and mud. Semi-dressed stone masonry is characterized by one wall wythe (usually exterior) built using shaped stones; usually only the exposed stone surface is shaped. In some cases, stone masonry can be reinforced, usually with wood elements (wood-reinforced).
