Listed buildings are one of Scotland's greatest assets. From medieval castles to structures dating from the 1980s, they cover almost every aspect of life, and are the physical record of the nation’s social and economic past and present. Using specially commissioned photography, this collection of 20 postcards showcases some of the most fascinating structures granted listed status by Historic Scotland. Images ranging from the iconic red steel cantilevers of the Forth Rail Bridge, to the sumptuous and ornate facade of Duff House, celebrate the diversity of Scotland's unique architectural treasures.
