The twelfth century represents the height of Romanesque building, with thick walls, rounded arches, and bold CARVINGS defining the architectural character of the age. Chevron mouldings, billet patterns, and cushion capitals became common features of doorways and arcades. Many churches rebuilt during this period replaced earlier SAXON structures, absorbing their foundations while introducing a new architectural vocabulary that would remain visible even in heavily altered MEDIEVAL buildings.

Decorative programmes expanded significantly during this century. Figurative sculpture became more common, including early GARGOYLES, symbolic beasts, and stylised FIGURES. FONT from this period often display intricate arcading or biblical scenes, reflecting growing artistic sophistication. Early STAINED GLASS also emerged, though few examples survive intact. Later additions such as ROOD SCREEN in the C14 or MISERICORDS in the C15 frequently sit atop C12 structural frameworks, creating a layered architectural narrative.
