Visitors to the Pétrus Ký Mausoleum and Memorial House in Chợ Quán may notice another ornate mausoleum located just 100m east along Trần Hưng Đạo boulevard in Hẻm (Alley) 472.
This was built in 1914 to house the tomb of Dominique-Thomas Trịnh Khánh Tấn (died 1913), Honorary District Chief (Tri huyện Honoraire) of Chợ Quán.
Little is known of Tấn, other than the fact that he was a trusted official of the colonial administration who lived on the nearby avenue de l’église de Choquan (modern Trần Bình Trọng street). Today he is remembered principally for his book Học Tập Qui Chánh (SLND, Chợ Quán, 1906), which he wrote to help Vietnamese Roman Catholic children live an upright and useful life.
Buried either side of Tấn are his wife Lê Thị Gương (died 1922) and their daughter Trịnh Thị Thiết (died 1948). An altar is located behind the three tombs. Outside, above the entrance, is a Latin inscription from the Vulgate Bible, which reads: Beati mortui qui in Domino moriuntur, meaning “Blessed are the dead who die in [the grace of] the Lord.”
If the gate is locked, those wishing to enter the mausoleum should make their way round to the left of the mausoleum until they reach the Quỳnh Café at 474/9 and ask the owner, who is a descendant of Trịnh Khánh Tấn.
