The decades before the Conquest were prosperous for the elite, and there was great patronage of church building by figures such as Lady Godiva. Many cathedrals were constructed, including Westminster Abbey, although all these were subsequently rebuilt after 1066. Norman workers may have been imported for Westminster Abbey through the Norman Archbishop of Canterbury, Robert of Jumièges. Recent arguments and recent archaeological discoveries have raised the possibility that the 11th-century St George's Tower, Oxford, predates both the foundation of Oxford Castle and the Norman Conquest, and functioned as a gate tower commanding the western entrance into the pre-Conquest burh. If so, the tower was then incorporated into the Norman castle built on the site in the 1070s, instead of being constructed along with it as architectural historians have long assumed. It would thus be almost without parallel in England as a purely secular and defensive Anglo-Saxon structure (see below, Secular architecture).

H.M. Taylor surveyed 267 churches with Anglo-Saxon architectural features and ornaments. Architectural historians used to confidently assign all Romanesque architectural features to after the Conquest, but now realize that many may come from the last decades of the Anglo-Saxon kingdom. Typical Anglo-Saxon features include: long-and-short quoins; double triangular windows; narrow, round-arched windows (often using Roman tile);
