Fortified houses in Ireland: In Ireland at the end of the sixteenth and beginning of the seventeenth century, the Fortified House, along with the stronghouse, developed as a replacement for the tower house.  'Fortified Houses' were often rectangular, or sometimes U or L-shaped, three-storey structures with high gables and chimney stacks and large windows with hood mouldings.  Some examples have square towers at the corners.  The interiors were relatively spacious with wooden partitions and numerous fireplaces.  In a number of cases 'Fortified Houses' were built onto pre-existing tower houses.  'Fortified Houses' were protected by gun fire from the angle towers and bartizans, and were also provided with bawn walls with gunloops, towers and protected gateways.  'Fortified Houses' were built throughout Ireland by large landowners from a variety of backgrounds, such as the Old English Earl of Clanricarde who built Portumna Castle in County Galway; Gaelic lords such as MacDonogh MacCarthy, Lord of Duhallow, who built Kanturk Castle in County Cork; and Cromwellian soldiers such as Sir Charles Coote, who built Rush Hall in County Offaly.

Architecture of Scotland: Castles arrived in Scotland with the introduction of feudalism in the twelfth century.  Initially these were wooden motte-and-bailey constructions, but many were replaced by stone castles with a high curtain wall.  In the late Middle Ages new castles were built, some on a grander scale, and others, particularly in the borders, simpler tower houses. Gunpowder weaponry led to the use of gun ports, platforms to mount guns and walls adapted to resist bombardment.  Medieval parish church architecture was typically simpler than in England, but there were grander ecclesiastical buildings in the Gothic style.  From the early fifteenth century the introduction of Renaissance styles included the selective use of Romanesque forms in church architecture, as in the nave of Dunkeld Cathedral, followed more directly influenced Renaissance palace building from the late fifteenth century, beginning at Linlithgow.  The private houses of aristocrats adopted some of these features and incorporated features of Medieval castles and tower houses into plans based on the French Château to produce the Scots Baronial style.  From about 1560, the Reformation led to the widespread destruction of church furnishings, ornaments and decoration and in post-Reformation period a unique form of church emerged based on the "T"-shaped plan.
