Situated in a fertile plain at the foot of Mount Zerhoun, the sprawling remains of Morocco's oldest Roman site -- Volubilis -- have survived pillage and long periods of neglect.
After decades of decay, however, custodians of the now closely guarded ancient city have turned the page and are bringing back the tourists.
The site, nestled among olive groves near the city of Meknes, boasts a new museum and visitor centre and has been attracting hundreds of thousands of visitors.
They stroll along the main artery lined with porticoes and the remnants of vast mansions, whose mosaic floors testify to a prosperous past.
A triumphal arch, a classic symbol of Roman architecture, sits at the top of what once was the main compound.
Known in Arabic as "Oualili", the city was named a UNESCO World Heritage site in 1997.
The ancient city has "known several civilisations, from the Mauritanian era to the Romans through the Islamic period", according to Mohamed Alilou, topographer and assistant conservator of the site.
Volubilis was founded in the third century BC by a Moorish community, before being annexed by the Roman Empire in 42 AD.
At its peak, it would have counted up to 15,000 inhabitants.
Threatened by civil wars across the empire, the Romans evacuated the city in 285. It didn't regain its splendour until the arrival of Arab conquerors in the seventh century.
In the eighth century when the Idrisid dynasty erected the city of Fez as its new capital, Volubilis fell once more into disuse.
- Bacchus gone missing -
At the end of the 17th century, Sultan Moulay Ismail sent thousands of slaves to plunder Volubilis's marble columns for the construction of his palace in Meknes.
"On the track leading from Volubilis to Meknes, we found capitals (of columns) abandoned by slaves, who fled when they learnt that Moulay Ismail was dead," said Alilou, who has been watching over the site for more than 30 years.
Excavations at Volubilis began in 1915, along with research programmes and restoration work.
But renewed interest in the site brought with it looting, especially during the period of French colonial rule from 1912 to 1956.
One particularly striking case in 1982 made headlines when a marble statue of Bacchus -- the Roman god of wine -- disappeared.
In a desperate bid to find the relic, King Hassan II dispatched gendarmes who "interrogated, abused and beat" peasants who "didn't know Bacchus from Adam and Eve", according to Moroccan press reports.
The effort was in vain and the statue was never found.
"The people here are still traumatised," said a resident of nearby Moulay Driss Zerhoun.
Moroccan media frequently warn that the country's heritage -- archeological finds, mosaics and ancient coins -- is being looted.
But in Volubilis, Alilou says that looting is a thing of the past.
Today "the site is fenced off and well guarded", he said. "We have a team of 14 guards who work day and night, cameras are everywhere."
Mustafa Atki, another Volubilis conservator, said the whole issue of looting was "sometimes exaggerated".
Since the opening of its museum in 2013, the ancient city has attracted several hundred thousand visitors a year.
"In 2017, for the first time we past the 300,000 mark," said Atki.
Alilou said the ancient city covering 42 acres (17 hectares) has yet to reveal all of its secrets.
"A third of the site, especially the western quarter built in the Islamic era, has not been excavated," he said.
