Cupra Marittima, in Italy’s Marche region, is today a sleepy seaside town – but it was once a thriving and powerful outpost of the Roman Empire.

Close to the pristine beaches of the Adriatic coast lie the ruins of the ancient Cupra temple, where a new discovery has come to light. Last week, archaeologists recovered parts of the 2,000-year-old temple’s frescoed walls and ceiling, painted in blue, yellow, red, black and green hues and decorated with flowery garlands, images of candelabra and tiny palms.

Finding ancient Roman temples with the interiors “still covered in paintings” is “extremely rare,” said archaeologist Marco Giglio, the site’s research project coordinator and a professor at the University of Naples L’Orientale.

“It’s the first time that the ruins of a shrine painted with such a wide palette of colors in an incredibly well-preserved state – and with such rich, elaborate decorations – has been unearthed,” he claimed in a phone interview, adding: “Once we have cleaned and analyzed all the 100 fragments found and pieced them together, we hope it will give us a complete picture of what the temple once looked like.”

Giglio hopes that the discovery sheds new light on the engineering techniques used by the Romans. Studying the walls’ recurring decorative motifs may also help researchers further understand the city’s local economy.

“The chronology of the different styles and decorative elements could tell (us) a lot about the artisan shops active at the time,” he said. “And the patterns and motifs could highlight whether it was the work of just one atelier or more.”

Images of candelabra decorated the walls of the temple.

Unusual painting style

The Cupra temple, built at the start of the first century AD, was the spiritual hub of a strategically and commercially important city that helped the Romans control the Adriatic coast and its maritime trading routes. Excavation began in July and is being led by the University of Naples L’Orientale and Cupra Marittima’s town council, which oversees the archaeological park where the old city’s ruins are situated.

Unusually, the newly discovered wall paintings appear to have been created in the so-called Third Pompeian (or “ornamental”) style typically used to decorate rich households in Pompeii and Rome, rather than religious structures, according to Giglio.

The ancient sanctuary is thought to have had a sky-blue ceiling, while the lower part of the temple’s walls were painted yellow. Red, black and yellow squares were separated by images of candelabra and garlands, with green bands of color running horizontally along the walls.

“Recovering intact ancient wall paintings like these is very rare. Paint is hard to preserve across time due to humidity, and it’s also very hard to dig out correctly during an excavation,” said Ilaria Benetti, an archaeologist from Pisa and Livorno provinces’ Superintendence of Archaeology, Fine Arts and Landscape in a phone interview.

“The incredible state of preservation and integrity of the frescoed parts, and the extremely rich color palette used – particularly the bright sky-blue and pinkish-red – stand out as quite exceptional when compared to the traditional red paint normally used in ancient times, thus suggesting it was a lavish shrine,” added Benetti, who is a frescoes expert but was not directly involved in the excavation.

Giglio added: “The sky-blue color is very rare for ceilings, which leads us to believe it was meant to indicate the celestial vault and that the shrine was built to honor a goddess.”

Although the temple shares a name with Cupra, an Etruscan goddess later incorporated into Roman religion, archaeologists have yet to determine which cult was associated to the shrine. A large statue of a goddess was likely kept in the main cell for worshippers, said Giglio.

Over time, most of the temple was destroyed, though the podium and a staircase leading to the entrance have survived. The rest of the shrine has been reduced to a heap of fragments lying one meter (more than three feet) below the ground, where archaeologists began digging earlier in the summer.

Research into the temple began in 2015, following a partnership between the Cupra archaeological park and the University of Naples L'Orientale. The temple will eventually be incorporated into the wider site, which gives visitors access to the Roman city's ruins.

The temple underwent several radical changes after its foundation, making it harder for Gilgio’s team to envision what it originally looked like. In 127 AD, the Roman emperor Hadrian funded a complete overhaul of the shrine as he feared it might collapse due to structural damage caused by aging or natural disasters.

To reinforce the structure, Hadrian is thought to have had the painted walls chiseled off and covered in marble. This process pulverized the original colored sections but they were later used as a base for the new floors. “That’s why the fragments recovered have been so well preserved, because their life was indeed short, roughly only a hundred years,” said Giglio, noting that this detail supports the idea that Roman builders recycled materials.

Hadrian then added nine-meter high columns with ornate capitals, semi columns and lion-headed roof dripstones, some parts of which have now been found. He also built two brick arches that still flank the temple site.

According to Giglio, Hadrian’s pagan masterpiece was later crushed to pieces starting from the 7th century. The marbles and columns were knocked down to be used as building materials, while at the end of the 19th century the temple walls were demolished to make room for a since-abandoned rural house that still looms over the shrine’s ruins.

Fragments of the shrine lie one meter (more than three feet) below ground.

“The house was actually built by incorporating part of the sanctuary’s walls, so we’re still trying to figure out whether it is best to restore it or take it down to recover the shrine in its entirety,” said Giglio.

With just one fifth of the temple site excavated thus far, the archaeologist said his team has had “just a taste” of what’s to come.

“Who knows what other decorations, patterns and elements could come to light?” he said. “It would be great that what we will unearth will lead to understand exactly how a construction site worked back in ancient Roman times.”
