Cultural heritage research focuses on the study and preservation of tangible and intangible aspects of a society's history and identity. This includes artifacts, buildings, traditions, beliefs, languages, and customs that have been passed down through generations. Researchers in this field often explore the significance of different cultural heritage elements, how they have evolved over time, and their impact on contemporary society. Preservation efforts in cultural heritage research aim to safeguard these elements for future generations and promote an understanding and appreciation of diverse cultures worldwide.
