The architecture of Scotland exists in many forms. In Mousa to Mackintosh, Frank Arneil Walker examines the recognisable and recurring features evident in Scotland's buildings across the centuries to build a picture of 'Scottishness' in architecture.

This chronological history presents an expansive view of architecture in Scotland, from neolithic brochs and classical country houses to baronial tower-houses and modernist New Towns, including the work of renowned architects such as Charles Rennie Mackintosh, Robert Adam, Basil Spence and Robert Lorimer. Walker considers the relationship between national characteristics and international influences in these structures to ask: what is the 'Scottishness' of Scottish architecture?
