From about 1560, the Reformation revolutionised church architecture in Scotland. Calvinists rejected ornamentation in places of worship, seeing no need for elaborate buildings divided up for the purpose of ritual. This resulted in the widespread destruction of Medieval church furnishings, ornaments and decoration. New churches were built and existent churches adapted for reformed services, particularly by placing the pulpit centrally in the church, as preaching was at the centre of worship. Many of the earliest buildings were simple gabled rectangles, a style that continued into the seventeenth century, as at Dunnottar Castle in the 1580s, Greenock (1591) and Durness (1619). These churches often have windows on the south wall (and none on the north), which became a characteristic of Reformation kirks. There were continuities with pre-Reformation materials, with some churches using rubble for walls, as at Kemback in Fife (1582). Others employed dressed 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.
