The Father Diệp Shrine at Tắc Sậy (Nhà Thờ Cha Diệp, also called Trung tâm Hành hương Tắc Sậy) in Giá Rai district, Bạc Liêu province, is the largest Catholic pilgrimage site in the Mekong Delta. The site commemorates Phanxicô Xaviê (Francis Xavier) Trương Bửu Diệp (1897-1946), a priest born in Cồn Phước, An Giang, ordained in 1924 after seminary studies partly in Cambodia, who took over the Tắc Sậy parish in 1930 and served its community - Catholic and non-Catholic alike - for 16 years with a reputation for simplicity and closeness to the poor.
Father Diệp's Death in 1946
During the unrest of 1946, Father Diệp chose to stay with his parishioners rather than flee, and was killed on 12 March that year.
Beatification
His cause for beatification was formally completed in 2019, and on 25 November 2024 the Vatican recognised his death as an act of martyrdom. On 2 July 2026, a formal Beatification Mass was held at the Tắc Sậy Pilgrimage Centre - the first beatification ceremony ever held on Vietnamese soil - presided over by Cardinal Luis Antonio G. Tagle on behalf of the Holy See, drawing an estimated tens of thousands of pilgrims.
A Pilgrimage Site
Long before that formal recognition, though, the shrine had already become a major pilgrimage destination for Vietnamese Catholics across the south, with pilgrims travelling from across the Mekong Delta and beyond seeking intercession for illness, hardship, and healing at his tomb.
