Ancient architecture is a field of academic research and historical study focused on the built environments, structures, and construction practices of past civilizations prior to the modern era. It investigates the materials, techniques, forms, functions, and symbolic meanings of buildings and urban spaces from antiquity, analyzing them within their specific cultural, social, technological, and environmental contexts. This interdisciplinary concept draws upon archaeology, history, art history, and engineering to illuminate the development of human societies, technological innovation, and cultural expression through their enduring physical legacies.
