Kathmandu Valley

The Kathmandu Valley is a bowl-shaped basin in central Nepal, set at roughly 1,400 metres above sea level and encircled by green hills such as Shivapuri, Phulchowki, Nagarjun, Chandragiri and Champadevi. The Bagmati River and its tributaries drain the valley, and the indigenous Newar people built three royal cities around its medieval kingdoms: Kathmandu, Patan (Lalitpur) and Bhaktapur. Human settlement and religious building in the valley stretch back almost two millennia; Licchavi-period stone inscriptions and monuments survive from the early centuries of the Common Era, and the valley flourished as a hub of Himalayan trade and craftsmanship under successive dynasties.

The Licchavi dynasty (whose earliest dated inscriptions reach back to the fifth century CE) and the later Malla dynasty (roughly the twelfth to eighteenth centuries) shaped the valley's temples, palaces and urban form, with the Malla period producing the great Durbar Squares as the three cities competed in artistic patronage. In the eighteenth century Prithvi Narayan Shah of Gorkha conquered the valley, unifying it into the modern state of Nepal and making Kathmandu the national capital.

UNESCO inscribed the Kathmandu Valley on the World Heritage List in 1979 (reference no. 121) under cultural criteria (iii), (iv) and (vi). The property is defined not as a single contiguous area but as seven distinct Monument Zones, which together cover about 189 hectares and are surrounded by a buffer zone of roughly 2,394 hectares. The boundaries were redefined into these seven zones during the 2000s to give clearer legal protection to the core monuments.

The inscription is illustrated by seven groups of monuments and buildings. Three are the Durbar (palace) Squares of the royal cities: Hanuman Dhoka in Kathmandu, the Durbar Square of Patan (Lalitpur), and the Durbar Square of Bhaktapur, each a dense ensemble of former royal palaces, courtyards, multi-tiered pagoda temples, stone sculptures and public water spouts. Two are the great Buddhist stupas of Swayambhu (the hilltop stupa overlooking Kathmandu) and Bauddhanath (Boudhanath), one of the largest stupas in the world and a centre of Tibetan Buddhist life. The remaining two are the Hindu temple complexes of Pashupatinath, the foremost Shiva temple of Nepal on the banks of the Bagmati, and Changu Narayan, a Vishnu temple noted for some of the valley's oldest stone inscriptions and carvings.

The monuments embody the highly developed craftsmanship of the Newars in brick, carved timber, stone and cast bronze. The valley's signature form is the multiple-roofed pagoda temple, a tiered timber-and-brick structure whose influence is often traced across Asia. Alongside the pagoda, the zones display the hemispherical stupa, the tower-like shikhara temple and the small votive chaitya, so that within a few square kilometres the full repertoire of Himalayan Hindu and Buddhist religious architecture is on view.

The Newar civilisation that created these monuments remains a living culture. Nepal Bhasa (Newari) is still spoken in the valley, the temples are active places of worship rather than museums, and the Durbar Squares continue to host daily ritual, festivals and markets, giving the property its character as a living heritage landscape.

The Kathmandu Valley is recognised as one of the world's great concentrations of religious art and architecture, representing the artistic and social achievements of the Newar people over many centuries. Criterion (iii) reflects the way the monuments bear exceptional testimony to the traditional Newar civilisation; criterion (iv) recognises the Durbar Squares and temple ensembles as outstanding examples of the architecture and town-planning of a Himalayan kingdom; and criterion (vi) acknowledges the valley's deep association with living Hindu and Buddhist traditions and the festivals, pilgrimages and rituals that animate the monuments.

What sets the property apart is the coexistence and intermingling of Hinduism and Buddhism within a single cultural landscape, expressed in shared shrines, overlapping deities and a continuous tradition of pilgrimage. The seven zones contain only a fraction of the valley's heritage; the wider basin holds well over a hundred significant monuments, courtyards and shrines, making the entire valley an unusually dense cultural region. This combination of artistic refinement, religious continuity and urban completeness is the basis of its outstanding universal value.

Rapid, often unregulated urban growth in the late twentieth century eroded the historic fabric around the monuments, and in 2003 UNESCO placed the Kathmandu Valley on the List of World Heritage in Danger, citing the partial or substantial loss of traditional elements in six of the seven monument zones and a resulting loss of authenticity and integrity. Over the following four years the Government of Nepal redefined the property boundaries, established buffer zones and put in place an Integrated Management Plan and coordinated management system for the zones. On the strength of these measures the World Heritage Committee removed the valley from the danger list on 25 June 2007 at its session in Christchurch, New Zealand, praising Nepal's efforts to manage urban development pressures.

The valley's heritage suffered a major blow in the earthquake of 25 April 2015, when, according to UNESCO assessments, more than thirty monuments collapsed and well over a hundred were damaged across the monument zones. Iconic structures were lost or severely harmed, including the Kasthamandap pavilion in Kathmandu Durbar Square (from which the city takes its name) and temples in Bhaktapur and Patan Durbar Squares; the historic Dharahara tower in central Kathmandu also collapsed with heavy loss of life. Extensive reconstruction has followed, much of it using traditional materials and Newar craft techniques.

Ongoing conservation challenges include earthquake reconstruction and seismic resilience, air and river pollution affecting sites such as Pashupatinath on the Bagmati, intense urbanisation and traffic, tourism pressure, and the need to balance the demands of a living religious city against the protection of its historic structures.

The seven monument zones lie within and around the three cities of the Kathmandu Valley and are easily reached from the capital. Kathmandu Durbar Square (Hanuman Dhoka), Swayambhunath and Pashupatinath are in Kathmandu itself; Patan Durbar Square is in adjoining Lalitpur, a short ride across the Bagmati; Bhaktapur Durbar Square and the Changu Narayan temple lie to the east of the city; and the great stupa of Boudhanath is in the north-eastern part of Kathmandu. Most can be combined over two or three days, and the Durbar Squares, Swayambhu, Boudhanath and Pashupatinath charge entry fees that help fund conservation.

Because the sites are active places of worship, visitors are expected to dress modestly, remove shoes where required, walk clockwise around stupas and chaityas, and observe restrictions at Hindu shrines. At Pashupatinath the inner temple is generally open only to Hindus, and the riverside ghats where cremations take place should be treated with particular respect. Photographing rituals, cremations and worshippers should be done discreetly and only where permitted, and signage at each site indicates restricted areas.
