During the 17th century the continuing advance of Classical forms overrode the eclecticism of English Renaissance architecture, which gave way to a more uniform style derived from continental models, chiefly from Italy. This entailed a retreat from the structural sophistication of Gothic architecture to forms derived from the more primitive construction methods of Classical antiquity. The style was typified by square or round-headed windows and doors, flat ceilings, colonnades, pilasters, pediments and domes. Classical architecture in England tended to be relatively plain and simple in comparison with the contemporaneous Baroque architecture of the continent, being influenced above all by the Palladian style of Italy. This was first introduced to England by Inigo Jones and typified by his Queen's House at Greenwich.
