The restoration of the temple of Banteay Srei marked a critical shift in how Khmer monuments were preserved, as Henri Marchal implemented the technique of anastylosis for the first time in Cambodia. By adopting methods observed during his 1930 visit to the Dutch East Indies, he moved beyond previous consolidation efforts to systematically reassemble historic stonework.
Early Training and Colonial Service
Born in the 6th arrondissement of Paris in 1876, Henri Marchal pursued architectural studies at the École des beaux-arts. He attended the workshop of Gaston Redon and completed his baccalauréat in 1895. In 1905, he began his long association with Cambodia as an Inspector of civilian buildings. By 1910, he had earned a Khmer language license and accepted a position as assistant curator at the Ecole française d'Extrême-Orient (EFEO) museum in Phnom Penh. His regional duties expanded in 1912 when he moved to Saigon to serve as an Inspector of civilian buildings for Cochinchina.

In 1916, following the death of Jean Commaille, Marchal was dispatched to manage the Conservation d'Angkor for the EFEO. He oversaw extensive clearing and excavation projects at major sites including Angkor Wat, the Bayon, the Baphuon, and Phimeanakas. Appointed a permanent member of the EFEO and curator in 1919, he led excavations at locations such as Ta Prohm, Preah Khan, and Phnom Bakheng. His administrative tenure spanned several decades, punctuated by his leadership in the archaeological service and his role as technical advisor to the Kingdom of Laos between 1954 and 1957.
Research and Scholarly Legacy
Marchal documented his observations through numerous technical publications and guidebooks. His bibliography includes detailed studies on Angkor Thom, the royal palaces, and comparative architecture across India and the Far East. Beyond his fieldwork, he authored works such as the 1928 Guide archéologique aux temples d'Angkor and the 1951 study Le décor et la sculpture khmers. In 1938, he led an archaeological mission in Arikamedu, India, further contributing to his extensive body of research on Eastern heritage.
Later Life and Final Years
Retiring in 1957, Marchal chose to remain in the region where he had spent the majority of his professional career. He settled in Siem Reap, Cambodia, maintaining his connection to the landscape he helped restore for over a decade. He resided there until his death in 1970 at the age of 93.
