Early postcards offer a fascinating visual insight into history. This book illustrates just some of the wide variety of iron churches, missions halls and chapels built by the early Victorian engineers to satisfy the needs of the religious revivals of the 19th century. Corrugated iron provided one of the best ways of erecting temporary buildings and manufacturers were quick to identify its potential. As we can see today, many of these 'temporary' buildings managed to survive far longer than their builders.
