This architectural style was often employed for public buildings, such as Aberdeen Grammar School (about 1860). However, it was by no means confined to Scotland and is a fusion of the Gothic revival castle architecture first employed by Horace Walpole for Strawberry Hill and the ancient Scottish defensive tower houses. In the 19th century it became fashionable for private houses to be built with small turrets. Such buildings were dubbed "in Scottish Baronial style". In fact the architecture often had little in common with tower houses, which retained their defensive functions and were deficient with respect to 19th-century ideas of comfort. The revival often adapted the style to the needs and technical abilities of a later time.
