For years, visitors would venture up Mount Sinai with a Bedouin guide to watch the sunrise over the pristine, rocky landscape or go on other Bedouin-led hikes. Now one of Egypt's most sacred places - revered by Jews, Christians and Muslims - is at the heart of an unholy row over plans to turn it into a new tourism mega-project. Known locally as Jabal Musa, Mount Sinai is where Moses is said to have been given the Ten Commandments. Many also believe that this is the place where, according to the Bible and the Quran, God spoke to the prophet from the burning bush.

The 6th century St Catherine's Monastery, run by the Greek Orthodox Church, is also there - and seemingly its monks will stay on now that Egyptian authorities, under Greek pressure, have denied wanting to close it. However, there is still deep concern about how the long-isolated, desert location - a Unesco World Heritage site comprising the monastery, town and mountain - is being transformed. Luxury hotels, villas and shopping bazaars are under construction there.

The project may have been presented as desperately needed sustainable development which will boost tourism, but it has also been imposed on the Bedouin against their will, says Ben Hoffler, a British travel writer who has worked closely with Sinai tribes. This is not development as the Jebeleya see it or asked for it, but how it looks when imposed top-down to serve the interests of outsiders over those of the local community, he told the BBC.

A new urban world is being built around a Bedouin tribe of nomadic heritage, he added. It's a world they have always chosen to remain detached from, to whose construction they did not consent, and one that will change their place in their homeland forever.

Egypt began its state-sponsored Great Transfiguration Project for tourists in 2021. The plan includes opening hotels, eco-lodges and a large visitor centre, as well as expanding the small nearby airport and a cable car to Mount Moses. The government is promoting the development as Egypt's gift to the entire world and all religions.

While work does appear to have stalled, at least temporarily, due to funding issues, the Plain of el-Raha - in view of St Catherine's Monastery - has already been transformed. Construction is continuing on new roads. This is where the followers of Moses, the Israelites, are said to have waited for him during his time on Mount Sinai. And critics say the special natural characteristics of the area are being destroyed.

Back in 2023, Unesco highlighted its concerns and called on Egypt to stop developments, check their impact and produce a conservation plan. This has not happened. In July, World Heritage Watch sent an open letter calling on Unesco's World Heritage Committee to place the St Catherine's area on the List of World Heritage Sites in Danger. Campaigners have also approached King Charles as patron of the St Catherine Foundation, which raises funds to help conserve and study the monastery's heritage with its collection of valuable ancient Christian manuscripts. The King has described the site as a great spiritual treasure that should be maintained for future generations.

The mega-project is not the first in Egypt to draw criticism for a lack of sensitivity to the country's unique history. But the government sees its series of grandiose schemes as key to reinvigorating the flagging economy. Egypt's once-thriving tourism sector had begun to recover from the effects of the Covid-19 pandemic when it was hit by the brutal war in Gaza and a new wave of regional instability. The government has declared an aim of reaching 30 million visitors by 2028.
