The speed at which the world is changing is astounding. No sooner is some state-of-the-art machinery or technology developed, there’s a new generation of advancements that can make it outdated. If you are using the iPhone 14, chances are kids might tell you it's an old model since the iPhone 15 is available on the market.

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.

Studying history provides us with valuable insights, which help us make informed decisions and shape a more progressive future. And photos like these offer a glimpse into how things were back in the day.

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.

Additionally, safeguarding also helps us to promote sustainability as we are reusing existing structures, and preserving natural resources. When monuments are cared for properly, they can be open for public viewing, allowing for the continued appreciation of our past. Sometimes it also helps to generate economic benefits as it creates jobs.

A place has to go through a comprehensive evaluation process in order to be approved for historical preservation. Firstly, the site should represent a notable period, event, or figure in history. For instance, it could have a unique architectural style or technique that represents a specific era or culture.

After that, the physical condition of the site is evaluated. This is done to determine the extent of preservation needed. Historians, archaeologists, and other experts also usually review the site.

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.

Many countries even have national and local laws that protect historic places. After much research and evaluation, an official nomination is prepared. There is a set of criteria for the selection to be accepted.

The final nomination is reviewed by relevant authorities or committees. In the case of international designations, it could be UNESCO.

Then the relevant officials create a plan that outlines how the site will be preserved, managed, and maintained. After this, the funding is secured to finally start the process. Once historical preservation takes place, there is a continual assessment to ensure the site’s preservation efforts are effective.

Some of such sites include the Great Wall of China in China, Machu Picchu in Peru, the Colosseum in Italy, the Pyramids of Giza in Egypt, the Acropolis in Greece, the Alhambra in Spain, and Stonehenge in England, among many others.

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.

Visiting historical sites or looking at vintage photos helps us celebrate the unique people and heritage of our neighborhoods and cities. They transport us back to a time when things were so different. Did you enjoy looking at these pictures? Which one of them was your favorite?
