The Church was constructed in 1821 during the reign of King Rama II upon the request of Father Pascal, a French Missionary. As the principal church of the Archdiocese of Bangkok, it plays a special role as the venue for important events in the Catholic Church of Thailand. This is where most ordinations of new priests and bishops occur. Also, members of the monarchy and high government officials come to visit this church to attend important ceremonies.
In 1984, Pope John Paul II (now, Saint John Paul II) visited this church. On November 22, 2019, Pope Francis held a mass and met with the youth inside the cathedral.
