From being the leading port town in Ancient Greece, to a modern city with a growing population and constant traffic, the surroundings of the Propylaea have changed a lot since it was first installed. The fumes and pollution created by the traffic, factories and large tourist industry (who want to see the Acropolis) have worn down the surface of the rock and marble of the Propylaea. It was even damaged by the landing and taking off of aircraft (now forbidden to fly over the Acropolis). The marble has suffered chemical change at an alarming pace. Ways to solve this are being devised. Before the 2004 Olympic games in Athens (which would have affected the external surroundings), the Propylaea was shrouded in scaffolding as restoration work was undertaken. All scaffolding was removed in the end of 2009 and the building can now be fully viewed. The famous ceilings have been partly
