The contents align with the Sustainable Development Goals (SDG 11), Target 11.4 which aims to "strengthen efforts to protect and safeguard the world's cultural and natural heritage'. This would ensure that a rich piece of history is documented and analysed to ensure that it is not erased and forgotten. This book serves as a bountiful data base of literature as well as conservation strategies for heritage conservationists, students of architectural conservation and researchers.
