In the shadow of the 1945 atomic blast that scarred Nagasaki, whispers of a profound secret linger amid the Peace Park's solemn monuments
You are a UNESCO special envoy, dispatched to Nagasaki in 1955, tasked with documenting the city's profound sites of resilience.
Your quest begins at the Monument of the Twenty-Six Martyrs
Delve into the layers of memory in Nagasaki, a martyr city where faith and peace have forever marked history.
Your journey in Nagasaki begins at the Monument of the Twenty-Six Martyrs of Japan, erected in 1962 in Nishizaka. This monument, approximately 6 meters high, honors the 26 Christians crucified on February 5, 1597, by order of Toyotomi Hideyoshi. Among them were Japanese, Spanish, Portuguese, and Mexicans, including Saint Paul Miki. This commemorative site is adjacent to Nishizaka Park, the exact location of the executions, marking the beginning of Christian persecutions in Japan after the 1587 ban. As an archivist, you collect the first fragments of this story of faith and sacrifice.
Continue your visit of Nagasaki towards Ōura Cathedral, a national historic monument. Consecrated in 1864, it was the first Gothic-style wooden Catholic church in Japan, built by French missionaries. Its bell tower rises 25 meters, and its total dimensions are 30m x 18m. This Important Cultural Property, visible from the Monument of the Twenty-Six Martyrs, was partially destroyed by the atomic bomb in 1945 and then rebuilt, symbolizing the resilience of the Christian community of Kyushu in the face of adversity.
The route then takes you to Hypocenter Park, established in 1955. This park marks the epicenter of the atomic bomb that exploded 500m above ground on August 9, 1945, causing the immediate death of over 74,000 people according to official city archives of Nagasaki. A white column indicates the exact hypocenter, in the heart of a 0.5-hectare park. Located approximately 1.2 km from the Monument of the Twenty-Six Martyrs, this site offers a striking contrast between the 16th-century religious persecution and the 20th-century nuclear catastrophe, two events that profoundly marked Nagasaki's history.
A short walk, about 500m from Hypocenter Park, leads to Nagasaki Peace Park, inaugurated in 1955 and covering 13 hectares. The Peace Statue, 9.7 meters high and created by Kitamura Seibo in 1955, dominates the site, its right arm raised symbolizing the call for peace. The pillars of the Peace Gate bear an inscription for eternal peace. This park is a powerful testament to Nagasaki's will to transform tragedy into a universal message of hope, an essential step to understanding the city's UNESCO World Heritage.
Your exploration concludes at Urakami Cathedral, dedicated in 1925. Rebuilt in 1959 after its near-total destruction by the 1945 atomic bomb (only 500m from the hypocenter), it was the largest Catholic church in Japan until 1958. Its towers rose 64 meters. The concrete core of the building, which resisted the explosion, is now evidence exhibited in the museum. This site, 300m from Peace Park, completes your thematic circuit through Nagasaki, leaving you with a deep understanding of this city's silent memory and its role in Kyushu's history.
