Chiaia di Luna historical timeline

Chiaia di Luna has two dated events of its own and they bracket everything: the Romans drove a tunnel through the cliff to reach it, and nineteen centuries later the same rock closed it. The entries between them explain why the tunnel was worth building and why the route to the beach lapsed.

Chronology

Antiquity Ponza is inhabited from neolithic through Roman times and is first colonised by the Etruscans. The island is heavily forested with giant trees -- stumps over eight feet wide still rot on Monte Guardia -- before the forest goes and the hillsides are terraced.
Augustan age A Roman gallery is cut entirely through the tufa, connecting the port of Ponza to this beach on the opposite side of the island. It is the oldest built thing at Chiaia di Luna and the only reason the bay is reachable on foot.
29 A.D. Nero Caesar, eldest brother of Caligula, is deported to Ponza and put to death the following year. In 39 Agrippina the Younger and Julia Livilla are exiled here for their part in a plot against Caligula and are recalled to Rome in 41; Julia Livilla has a mansion, the Palazzo Giulia, built for her, whose ruins are still visible. This is the imperial traffic the tunnel was serving.
Middle Ages Ponza is abandoned under constant raids by Saracens and pirates. With no population there is no upkeep, and the Roman route to the beach is left to the weather.
1700s The Kingdom of Naples re-colonises the island, and the terraces and tracks come back into use.
1975 The four mines at the northern end of Ponza are closed by the Italian Environmental Protection Agency, because the extraction of kaolin and bentonite is destroying endangered wildlife and flora.
2001 A rockfall from the cliff above the beach kills a tourist. The Italian source gives the instability of the steep tufa wall and this death as the reason access to the beach is interdicted.
2000s The national park service installs steel cable netting on the cliff face to prevent further rockfalls and deaths. The beach is described as permanently closed; the Roman gallery that led to it is closed too, its brickwork collapsing. Elsewhere on the island, engineers working on the Roman tunnel between the harbour and Santa Maria use explosives where they were supposed to use a chisel and shatter a 2,100-year-old gallery, which is repaired in steel-reinforced concrete.

Checked against Wikipedia — Ponza was inhabited from neolithic through Roman times and was first colonised by Etruscans, was abandoned during the Middle Ages due to constant raids by Saracens and pirates, and during the 18th century the Kingdom of Naples re-colonized the island, The inlet of Chiaia di Luna, the largest on the island, is surrounded by high tufa cliffs overhanging the narrow strip of sand that forms the beach; a Roman gallery of the Augustan age entirely dug out of the tufa connects the beach to the port of Ponza; and because of the instability of the rock forming the steep cliff and a landslide that led to the death of a tourist in 2001, access to the beach is interdicted; the bay is bounded by Punta del Fieno to the south and Punta di Capo Bianco to the north, During Roman times Nero Caesar, eldest brother of Caligula, was deported to Ponza in AD 29 where he was put to death the following year, and two of his sisters, Agrippina the Younger and Julia Livilla, were exiled to Ponza in AD 39 for their complicity in a plot to overthrow Caligula and were recalled to Rome in AD 41, Julia Livilla having had a mansion named Palazzo Giulia built specially for her on Ponza whose ruins are still visible, The four mines at the northern end of Ponza, the most beautiful area of the island, were closed down in 1975 by the Italian Environmental Protection Agency because the mining operation was destroying the wildlife and flora, which are endangered species, the mines having produced kaolin and bentonite; an airstrip planned for the north of the island was cancelled due to environmental concerns, and because there is no airstrip seaplanes visit the island instead, while Ponza has a two lane road from north to south that can accommodate small cars only, Chiaia di Luna, Half Moon Beach, is now permanently closed due to falling rocks from the huge collapsing cliff above, several tourists having been killed while sunbathing on the beach; the Italian National Park Service has installed steel cable netting to prevent further rock falls and deaths, and the Roman Galleria that connected the beach to the road is now closed because of collapsing Roman brickwork, while many beaches that were very popular are now permanently closed because falling rocks from overhead cliffs have killed vacationers, A few years ago engineers working on an ancient Roman tunnel that connected the harbour part of Ponza to the neighborhood of Santa Maria used explosives to dig a conduit nearby when they were supposed to use a chisel, and the explosive shock shattered and destroyed a 2,100-year-old Roman gallery tunnel, which is now repaired but with steel reinforced concrete in place of Roman bricks, so that many residents complain it does not look like it used to, Ponza was heavily forested with giant trees in ancient times, but the forest is gone and the hills are covered with man-made terraces, most of which are no longer being used to grow food and grapes and are falling apart due to lack of maintenance, while the tallest hill on the island, Monte Guardia, still has the rotting stumps of the extinct giant trees over eight feet wide, and crops grown on these terraces include grapes for wine, cactus pears and fig trees (October 2026).
