About: Pit alignments

Pit alignments are a type of prehistoric monument found throughout the British Isles, the function of which is at present poorly understood. They consist of a series of evenly spaced and often relatively shallow pits arranged in lines. These monuments are most frequently discovered through aerial photography, being morphologically well suited to identification by this method. Some alignments run for large distances, in straight or curving lines, and clearly represent massive undertakings by large numbers of people or by smaller numbers over long periods of time. Some examples appear to have been left open for some time rather than being immediately backfilled and do not appear to have held timber posts; they can sometimes be seen to interact with other pre-existing monuments.
