These rapid changes are happening in almost every discipline—engineering, science, medicine, and architecture, amongst others. But here’s the thing: while we must change with the times, it’s also important to preserve our history. In order to preserve a tangible physical connection to the past, several historical monuments have been protected and maintained over the years using historic preservation. By doing so we are able to gain understanding about the people and events that shaped our communities. Many cultural heritage sites, buildings, and structures link us to particular moments, locations, and occasions that marked important turning points in our shared past. They then provide their fair recommendations to the authorities. In some cases, even public opinion is sought to ensure that the site’s preservation is valued by the community. The final nomination is reviewed by relevant authorities or committees. In the case of international designations, it could be UNESCO. While these physical sites are a great way to relive the past, photographs from bygone eras show us how people worked, dressed, and did things back then. Follow Bored Panda on Google News!
