When brick production resumed in earnest on the British Isles, the 1½" to 2" height of the Roman-style brick gradually increased during the early Medieval period. Brick from the Ancient Roman Empire was commonly reused in medieval Europe as well as in later periods. This reuse can be found across the former Roman Empire. In Great Britain, where construction materials are less plentiful, Roman structures were quarried for their stone and brick and it was commonly reused. Examples of this type of reuse in Great Britain can be found in Anglo-Saxon churches at Brixworth, Corbridge, St. Martin's, Canterbury, and St Nicholas', Leicester, and also in St Albans Abbey church (now St Albans Cathedral).
