Greek archaeology emerged as a formal discipline in the late 18th century, evolving from unsystematic artifact hunting to a scientific field. Key developments included stratigraphy, typology, and the establishment of the Greek Archaeological Service in 1833. Major discoveries like Troy, Knossos, and the Athenian Agora revolutionized our understanding of ancient Greek civilization. Modern techniques, including geophysical prospection and 3D modeling, have enhanced archaeological research, while ethical concerns about repatriation and site preservation remain crucial challenges.
