Throughout the Plantagenet era, an English Gothic architecture flourished, with prime examples including the medieval cathedrals such as Canterbury Cathedral, Westminster Abbey and York Minster. Expanding on the Norman base there was also castles, palaces, great houses, universities and parish churches. Medieval architecture was completed with the 16th-century Tudor style; the four-centred arch, now known as the Tudor arch, was a defining feature as were wattle and daub houses domestically. In the aftermath of the Renaissance a form of architecture echoing classical antiquity synthesised with Christianity appeared, the English Baroque style of architect Christopher Wren being particularly championed.
