It is the result of an ancient and widespread practice (spoliation) whereby stone that has been quarried, cut and used in a built structure is carried away to be used elsewhere. The practice is of particular interest to historians, archaeologists and architectural historians since the gravestones, monuments and architectural fragments of antiquity are frequently found embedded in structures built centuries or millennia later. The archaeologist Philip A. Barker gives the example of a late Roman period (probably 1st-century) tombstone from Wroxeter that could be seen to have been cut down and undergone weathering while it was in use as part of an exterior wall and, possibly as late as the 5th century, reinscribed for reuse as a tombstone.

Entire structures, including underground foundations, are known to have been demolished to enable the construction of new ones. According to Baxter, two churches in Worcester (one 7th century and one 10th) are thought to have been deconstructed so that their building stone could be repurposed by St. Wulstan to construct a cathedral in 1084. And the parish churches of Atcham, Wroxeter, and Upton Magna are largely built of stone taken from the buildings of Viroconium Cornoviorum.
