Landscape archaeology, previously known as total archaeology is a sub-discipline of archaeology and archaeological theory. It studies the ways in which people in the past constructed and used the environment around them. It is also known as archaeogeography (from the Greek ἀρχαίος "ancient", and γεωγραφία "earth study"). Landscape archaeology is inherently multidisciplinary in its approach to the study of culture, and is used by pre-historical, classic, and historic archaeologists. The key feature that distinguishes landscape archaeology from other archaeological approaches to sites is that there is an explicit emphasis on the sites' relationships between material culture, human alteration of land/cultural modifications to landscape, and the natural environment. The study of landscape archaeology (also sometimes referred to as the archaeology of the cultural landscape) has evolved to include how landscapes were used to create and reinforce social inequality and to announce one's social status to the community at large. The field includes with the dynamics of geohistorical objects, such as roads, walls, boundaries, trees, and land divisions.
