In 1975, the Greek government launched a multidisciplinary project that addressed the deteriorating condition of the monuments of the Acropolis. Led by The Committee for the Conservation of the Acropolis Monuments (ESMA) and The Acropolis Restoration Service (YSMA), the ancient Athenian Acropolis has undergone extensive repair sessions to fulfill the long-term goal of restoring the site as close to antiquity as possible. Over the last few decades, the committees have worked together to commence interventions on 4 of the main buildings on the Acropolis – the Erechtheion, the Parthenon, the temple of Athena Nike, and the Propylaea – along with the circuit walls enclosing the Acropolis and other architectural members scattered across the site. More than 160 professionals in architecture, engineering, archaeology, technology, and administration carry out the research and groundwork for this extensive project. Today, restoration efforts are still underway, but much of the Acropolis is open to the public to experience one of the most preserved ancient sites in the world.
