Some followed the leadership of Father Jacques Corre, and settled on the west bank of the Chao Phraya River in the area now known as Kudi Chin where the Santa Cruz Church was soon established.

Another faction, who had refused to accept the authority of the French Mission, settled on the eastern bank in an area now known as Talat Noi within Samphanthawong District.

In 1822, the church finally established communion with the Holy See, coming under the authority of Bishop Esprit-Marie-Joseph Florens, the Vicar Apostolic of Siam.

The church employs Gothic-arched doors and windows throughout, and its stained glass work is among the most beautiful in Thailand.

The church is an unregistered ancient monument, and received the Association of Siamese architects' Architectural Conservation Award in 1987.
