The Acropolis of Athens is thousands of years old, so protecting it from damage is a constant challenge. The maintenance of the Acropolis is not a single project that happens once every few years. Restoration and conservation work has been continuing since the 1970s and is still taking place today. The main goal of the maintenance is to protect the ancient monuments while keeping as much of the original material as possible. Specialists work on the Parthenon, the Acropolis walls and other buildings. They carefully examine the marble, repair damaged parts and monitor the stability of the structures. Modern technology is also used to document the monuments and identify possible problems. One of the biggest challenges is the Parthenon. Restoration work there includes repairing parts of the walls, restoring architectural elements and replacing some damaged marble with new Pentelic marble, similar to the material used in ancient times. The work is designed to respect the original structure rather than completely rebuild the monument. In June 2026, an important part of the restoration was completed when scaffolding was permanently removed from the western side of the Parthenon. Two marble blocks were restored and placed in the western pediment, completing an important part of the monument after around 220 years. The current restoration programme also includes work on the fortification walls, conservation of marble surfaces and improvements to visitor access. The European Union reports that the programme is intended to support the long-term preservation of the Acropolis and includes measures against the effects of climate change. The maintenance of the Acropolis is therefore a continuous process. The aim is not to make the monuments look completely new, but to protect their historical character and make sure they survive for future generations. This is especially important because the Acropolis is not only one of Greece's most famous landmarks, but also a UNESCO World Heritage Site.
