A group or complex of fields which appear to form a coherent whole.

Within this category you have the following sub-types:
- Field System
- “Celtic” Field Systems – A fairly regular system of small rectangular fields. Examples may date from the middle Bronze Age to the Roman period. The word ‘Celtic’ carries no chronological or cultural connotations in this context.
- Co-axial field systems (with one prevailing axis of orientation, in which most field boundaries are either aligned with this axis or run at right angles to it)
- Ridge and Furrow
- A series of long, raised ridges separated by ditches used to prepare the ground for arable cultivation. This was a technique, characteristic of the medieval period.
- Strip Lynchet
- A terraced field usually found on hillsides. Comprising a flat strip of land, called the tread, and a steep, scarped lynchet (a bank formed at the end of a field by soil which, loosened by the plough, gradually moves down slope through a combination of gravity and erosion)
- Water Meadow
- Grassland fertilized by allowing floodwater to cover it in winter.
