Jan Letzel

Jan Letzel was a Czech architect whose work in the early 20th century linked Central European architectural practice with rapid modernization in East Asia. Trained in the Austro-Hungarian architectural milieu, he became notable for introducing Western architectural techniques to projects in Japan and for designing the building later known as the Hiroshima Prefectural Commercial Exhibition Hall, now the Atomic Bomb Dome. Letzel's career intersected with figures, institutions, and events across Prague, Tokyo, Hiroshima, Vienna, and Budapest.

Early life and education

Letzel was born in Tutov in Bohemia, then part of Austria-Hungary, and grew up amid the cultural and industrial transformations affecting Central Europe around the turn of the 20th century. He studied architecture in Prague at institutions influenced by professors and movements associated with Otto Wagner, Adolf Loos, and the broader Secession (art) currents connected to the Vienna Secession. During his formation he encountered the practices of firms and figures from Vienna, Budapest, Berlin, Munich, and St. Petersburg, which shaped his approach to masonry, ironwork, and reinforced concrete used across projects in Europe and Asia.

Architectural career

After completing his education, Letzel worked within networks that included ateliers and construction companies active in Vienna and Prague. He became involved with clients and collaborators from the Austro-Hungarian sphere, negotiating commissions that required familiarity with engineering advances promoted by companies like those in Brno and Graz. Letzel’s style drew on influences traceable to Josef Hoffmann, Otakar Novotný, and the technical vocabulary of the Industrial Revolution as mediated by firms in Germany and France. His professional path led him to accept opportunities overseas, aligning with the pattern of European architects working in Shanghai, Hong Kong, Manchuria, and Yokohama.

Works in Japan

Letzel relocated to Japan where he established a practice focused on commercial and civic architecture amid the Meiji period and Taishō period modernization efforts. He worked alongside local contractors and foreign firms involved in urban redevelopment in Tokyo, Yokohama, Osaka, and Hiroshima. His commissions connected him with clients from British trading houses, Austrian insurance companies, and Japanese prefectural governments, and his projects reflected technological exchanges similar to those between Charles Thomas Ashbee, William Morris, and continental practitioners working in Asia. Letzel produced designs for exhibition halls, office buildings, factories, and residences, engaging with materials and techniques promoted by manufacturers in England, Belgium, and Italy.

Hiroshima Prefectural Commercial Exhibition Hall (Atomic Bomb Dome)

Letzel’s most renowned work was the Hiroshima Prefectural Commercial Exhibition Hall, completed in the mid-1910s in Hiroshima. Commissioned during a period of urban expansion and civic pride, the design incorporated a brick-and-concrete structure and a dome influenced by European civic architecture seen in Prague, Vienna, and Berlin. The building became central to Hiroshima’s cultural life until it was destroyed by the Atomic bombing of Hiroshima on 6 August 1945, an event tied to World War II, the Manhattan Project, and diplomatic decisions involving United States leadership such as Harry S. Truman. The surviving ruins were later preserved as a memorial now known as the Atomic Bomb Dome, a site recognized by UNESCO World Heritage Site designation and visited by delegations, survivors, and figures from Japan, Czechoslovakia, United States, and elsewhere.

Later life and legacy

After his Japan period Letzel returned to Europe and died in Prague in 1925. His legacy endures through scholarship and preservation efforts connecting Czech, Japanese, and international historians, architects, and memorial organizations, including those from Hiroshima Prefecture and cultural institutions in Prague and Brno. The Atomic Bomb Dome has made Letzel’s name prominent in discussions involving architectural heritage, postwar reconciliation, and memorialization practices promoted by bodies such as UNESCO and civic groups in Hiroshima. Researchers trace lines between Letzel’s work and debates involving conservationists, architects, and urban planners from cities like Berlin, London, New York City, Beijing, and Seoul who study the interaction of built form, disaster, and memory.
