Greek authorities say a major restoration program has been successfully completed on the 2,500-year-old monumental gateway of the Acropolis.
The culture ministry says the 7-year project has lengthened the roof on the ancient marble building, known as the Propylaea.
The ministry also said Monday 255 blocks of marble were taken down from the monument so experts could remove rusting metal clamps used by previous restorers, which had caused extensive cracking.
The Propylaea is the only Acropolis monument to retain large sections of its ancient roofing.
The hilltop temples are undergoing extensive restoration, expected to continue beyond 2020.
