“A proud moment for every Indian!” Prime Minister Narendra Modi posted on the social platform X, minutes after the ancient Buddhist site of Sarnath was inscribed onto the UNESCO World Heritage List on Saturday evening in Busan, South Korea. His reaction, shared digitally across a nation of 1.4 billion, was one of several real-time celebrations as the 48th session of the World Heritage Committee conferred global status on a geographically disparate set of properties.

The committee, meeting through Wednesday, also inscribed a chain of seven Iranian mountain fortresses known as the Alamut strongholds, the archaeological landscape of Japan’s 6th- to 8th-century capitals Asuka and Fujiwara, Greece’s Mount Olympus as a mixed cultural and natural site, and South Sudan’s Boma-Badingilo migratory ecosystem – the young nation’s first entry on the list. Each application had been years, sometimes decades, in preparation: Sarnath had waited since 1998, Alamut since 2003, Asuka-Fujiwara since 2007.

Sarnath, near Varanasi in Uttar Pradesh, marks the spot where the Buddha delivered his first sermon after enlightenment – the “Turning of the Wheel of the Law.” Its Dhamekh Stupa, Ashokan pillar and sprawling monastic remains had long been on India’s tentative list; the successful nomination means three of the four principal Buddhist pilgrimage sites now hold World Heritage status, joining Lumbini in Nepal and the Mahabodhi Temple at Bodhgaya. In Iran, the Alamut file comprises seven fortresses that once formed the integrated defensive and administrative backbone of the Nizari Ismaili state. Hamideh Chubak, director of the Alamut Cultural Heritage Base, told local media that the citadel of Alamut itself served as the seat of rule, while nearby Lambsar was the winter residence of the deputy ruler. The site is also associated with the medieval polymath Khajeh Nasir al-Din al-Tusi, who studied there. For Japan, the 19 sites of the Asuka-Fujiwara cluster – palace foundations, Buddhist temples and keyhole-shaped tombs – have been exhaustively excavated yet remain largely invisible to the naked eye. Nara University archaeologist Yoshiyuki Aihara captured the paradox during a press briefing: “If you dig underneath these rice paddies about one metre, you start finding a stretch of ruins,” he said. The Takamatsuzuka tomb’s vividly coloured murals, designated a national treasure, were removed for conservation, a delicate process the committee urged Japan to continue researching.

The inscriptions triggered immediate expressions of national pride and the familiar hope of a tourist windfall. Greece’s delegate, Georgios Koumoutsakos, quoted mythology from the foot of newly hallowed Mount Olympus: “It is always best to remain on good terms with gods.” Evangelos Geroliolios, mayor of the Dion-Olympus municipality, acknowledged that the honour “places greater obligations on our part to protect this environment.” For South Sudan, the listing of a vast wetland-savanna landscape that hosts six million migratory antelopes – and sustains herding, farming and fishing communities – was framed by Unesco as a dual recognition of natural spectacle and harmonious coexistence. Yet behind the speeches, a quieter narrative endures: Sarnath was lost to forest until the 18th century, Alamut’s fortresses required two decades of field surveys, and the Asuka palaces still lie concealed beneath rice paddies, their contours visible only to archaeologists and the occasional probing spade.
