A stretch of garden wall ringing an ancient house in Pompeii gave way Tuesday after days of torrential rain, the latest structure to collapse at the popular archaeological site.

Pompeii officials said an inspection found that a 40-foot (12-meter)-long section of wall forming part of the perimeter of a garden area near the House of the Moralist gave way in several points. They said the extreme sogginess of the soil brought down the wall in an area that hasn’t been excavated near the house.

A few weeks ago, Italy was embarrassed when a frescoed house, the Schola Armaturarum, where gladiators prepared for combat, was reduced to a pile of stones and dust in seconds. Less than a year ago, another building, the House of the Chaste Lovers, collapsed in Pompeii.

The House of the Moralist wasn’t affected by the wall’s demise “and isn’t at risk for collapse,” Pompeii excavations director Antonio Varone said.

The House of the Moralist includes the remains of the homes of two families in the ancient city that was buried by the catastrophic eruption of Mount Vesuvius in 79 A.D. It is one of many structures in Pompeii that are off-limits to tourists, and no one was injured in the wall’s collapse, which was discovered early in the morning before opening hours.

Made of tufa rock, the garden wall was heavily damaged during the U.S. bombing of the Naples area in World War II. It was rebuilt after the war using a mix of the ancient stones and modern material, said Daniela Leone, an official of the state Naples and Pompeii Archaeological Superintendency.

Coincidentally, Carabinieri police were in the ruins when the garden wall came down. The officers were inspecting the gladiators house as part of efforts to pinpoint the cause of that collapse and decide if that structure can be reconstructed.
