A nucleated village or clustered settlement is one of the main types of settlement pattern. It is one of the terms used by geographers and landscape historians to classify settlements. It is most accurate with regard to planned settlements — its concept is one in which the houses, even most farmhouses within the entire associated area of land, such as a parish, cluster around a central church which is close to the village green. Other focal points can be substituted depending on cultures and location, such as a commercial square, circus, crescent, a railway station, park or a sports stadium.
