From about 1560, the Reformation revolutionised church architecture in Scotland. Calvinists rejected ornamentation in places of worship, with no need for elaborate buildings divided up by ritual, resulting in the widespread destruction of Medieval church furnishings, ornaments and decoration. There was a need to adapt and build new churches suitable for reformed services, particularly putting the pulpit and preaching at the centre of worship. Many of the earliest buildings were simple gabled rectangles, a style that continued to be built into the seventeenth century, as at Dunnottar Castle in the 1580s, Greenock (1591) and Durness (1619), but often with windows on the south wall (and none on the north), which became a unique feature of Reformation kirks. There were continuities with pre-Reformation materials, with some churches using rubble, as at Kemback in Fife (1582). Others employed stone and a few added wooden steeples, as at Burntisland (1592). The church of Greyfriars, Edinburgh, built between 1602 and 1620, used a rectangular layout with a largely Gothic form, but that at Dirleton (1612), had a more sophisticated classical style. A variation of the rectangular church that developed in post-Reformation Scotland was the T-shaped plan, often used when adapting existing churches, which allowed the maximum number of parishioners to be near the pulpit. They can be seen at Kemback and Prestonpans after 1595. It continued to be used into the seventeenth century as at Weem (1600), Anstruther Easter, Fife (1634-44) and New Cumnock (1657). In the seventeenth century a Greek cross plan was used for churches such as Cawdor (1619) and Fenwick (1643). In most of these cases one arm of the cross would have been closed off as a laird's aisle, meaning that they were in effect T-plan churches.
