The Maldives Heritage Survey is a collaboration between the Oxford Centre for Islamic Studies, the Earth Observatory of Singapore, SAIELab at Washington University in St Louis, and the National Center for Cultural Heritage under the Ministry of Arts, Culture and Heritage in the Maldives. The Maldives is an Indian Ocean archipelago of low-lying coral atolls that consists of 1192 islands, fewer than 200 of which are currently inhabited. The islands have been an important site on the historic maritime crossroads facilitating the circulation of peoples, goods and ideas across the Indian Ocean world—with significant commercial and cultural connections to Africa, Arabia, India, Sri Lanka, Indonesia and China. These islands have at various points been the location of Buddhist monastic communities, a Muslim sultanate beginning in the twelfth century (and visited by Ibn Battuta in the fourteenth), and a brief Portuguese occupation in the sixteenth, as well as in turns a Dutch and a British protectorate before the establishment of the modern state in 1968 (Feener Reference Feener, Fleet, Krämer, Matringe, Nawas and Rowson2021).

Beyond its broad outlines, the history of these islands is little known due to the lack of documentary sources available for its study. Since the pioneering work of Bell (Reference Bell1922), the ceramic sherd collection by Carswell (Reference Carswell1975), and the more systematic excavations done by Skjølsvold (Reference Skjølsvold1991) and Mikkelsen (Reference Mikkelsen1991, Reference Mikkelsen2000) following in the wake of Heyerdahl's (Reference Heyerdahl1986) ‘Maldive Expedition’, little archaeological work had been done until a recent wave of new activity in the field by Haour et al. (Reference Haour, Christie and Jaufar2016, Reference Haour, Christie, Jaufar and Vigoureux2017), Jameel (Reference Jameel2017), Pradines (Reference Pradines2018) and Jaufar (Reference Jaufar2019). An open-access library offering a fuller bibliography of publications is available on the Maldives Heritage Survey website. These excavations and architectural studies have produced a new level of detailed knowledge about several early Islamic sites. As a complement to these precision-focused investigations, our work provides the first ever comprehensive survey of the tangible cultural heritage of the Maldives. This enables us to map the spatial distributions of Buddhist, Islamic and other historic and archaeological sites across the entire country.

Completing this work is urgent as the low-lying islands of the Maldives face existential threats from climate change and other forms of environmental stress, as well as vulnerabilities to human acts of vandalism and destruction. These factors have motivated our work to locate, document and make an inventory of endangered tangible cultural heritage and to create an open-access and permanently archived record of the Maldivian past.

We conducted two years of full-time field survey from April 2018 until 2020. We surveyed 152 islands across six atolls (Figure 1) and documented over 292 sites with 1171 structures, 5761 small objects, in addition to digitising 410 manuscripts in Dhivehi and Arabic (Table 1). Sites were located using a combination of archival research, consultation with local communities and systematic field-walking. We documented each site with a combination of mapping and measurement, photography, field notes and oral histories. We used photogrammetry and a Faro Focus lidar station to record high-resolution 3D data for complex architectural features and select objects. The current condition of each site was evaluated and possible threats from environmental and other sources identified. Alongside the primary fieldwork, we also worked with institutions outside the Maldives to digitise relevant materials from their collections. Records for each site, structure and object, along with archives of digitised manuscripts, 3D visualisations and other resources, are open access on the project website. Full datasets for lidar scans of sites and structures are also made freely available through OpenHeritage3D. Project data are permanently archived within the Oxford Research Archive of the University of Oxford's Bodleian Library system.

Our work has contributed significantly towards generating new knowledge about the history of the Maldives, contextualising the limited work that had been done previously at a small number of select sites by creating a new map that spatialises historical patterns of settlement and the establishment of Buddhist and Islamic ritual sites across the archipelago. For purposes of illustration in this brief note we present some of our key findings by atoll.

Laamu

On the island of Gan a large artificial mound site had been documented by Bell (Reference Bell1922) in one of the rare earlier archaeological explorations of the Maldives. While Bell and his team identified nine structures on this site (Figure 2), our work there documented the ruins of dozens of additional structures and earthworks, allowing us to map the actual extent and spatial organisation of this major Buddhist ritual complex for the first time (Figure 3).

On the same island a coral stone boulder carved with a kala head on one face (Figure 4) and Sanskrit inscription of a Buddhist mantra on its reverse (Figure 5) was recovered for the Maldives National Museum.
