This book approaches the study from architectural perspectives, analyzing the collection of brochs' features and classifying them based on regional differences. By identifying regional standard models and hypothesizing design schemes, it reveals insights into the methods and strategies used by ancient builders. This understanding not only aids in interpreting brochs but also makes these uncertain archaeological sites more readable and accessible. The major conclusion of this book is the framework of interpretive conservation, offering practical guidance for the consolidation, restoration, and reconstruction of brochs. It advocates for holistic conservation projects that move beyond preservation, proposing dynamic changes to sites that enhance interpretation and public engagement. With its innovative approach and comprehensive analysis, this book is an indispensable resource for archaeologists, architects, and heritage professionals, offering ideas with potential applications to broader heritage conservation efforts worldwide.
