The Royal Archives is a collection of documents and records that belong to a monarchy, preserving important historical information about the royal family and the nation. These archives often include letters, official papers, and photographs that provide insights into the lives of monarchs and significant events in history. In the United Kingdom, for example, the Royal Archives at Windsor Castle houses documents dating back centuries, showcasing the evolution of the monarchy. Such archives are essential for researchers, historians, and the public, as they offer a glimpse into the past and help maintain the legacy of the royal institution.
