The (Roman Catholic) Diocese of Ratchaburi (Diœcesis Ratchaburensis, ) is a Latin suffragan diocese of the archdiocese of Bangkok in western central Thailand. The diocese covers an area of , covering four of the western provinces of Thailand: Ratchaburi, Phetchaburi, Kanchanaburi, and Samut Songkhram. As of 2001, of the 2.2 million citizens, 15,246 are members of the Catholic Church. It is divided into 17 parishes, having 71 priests altogether. While the cathedral episcopal see dedicated to the Nativity of Our Lady is at Bang Nok Khwaek, the diocesan center is in the town of Ratchaburi. History The diocese dates back to 30 June 1930, when the Mission sui iuris of Rajaburi was created, originally responsible for the south and west of Thailand, on territory split off from the then Apostolic Vicariate of Bangkok (now its Metropolitan). It was run by the Salesian order, who came there in 1927 and supplied the missionary Ordinaries. The 18 missionaries took over a mission previously run by the Paris Foreign Missionaries. On 28 May 1934 it was elevated to Apostolic Prefecture of Rajaburi; on 3 March 1941 to Apostolic Vicariate of Rajaburi, hence entitled to a titular bishop. On 18 December 1965 it became the Diocese of Bangnokhuek. On 21 October 1966 it was renamed Diocese of Ratburi. On 26 June 1969 the Diocese of Surat Thani was split off from the diocese (a fellow suffragan of Bangkok), which continued to be run by Salesians, while the remainder, again renamed Diocese of Ratchaburi, was since then under the responsibility of native priests. Cathedral The cathedral of the diocese is the Nativity of Our Lady Cathedral (Thai: อาสนวิหารแม่พระบังเกิด). It is in Bang Nok Khwaek, Amphoe Bang Khonthi, Samut Songkhram Province. The church is built in French Gothic style and decorated with stained glass windows imported from France. In two rows these show scenes of the life of Jesus in top row, as well as holy people (men to the north, women to the south). Around 1840 nine Chinese Catholic families moved to the rim of the Mae Klong River. The community grew to about 200 Catholics until 1847, when a first wooden church named Sala Daeng (Red Hall) or Raung Yao (Long Canal) was built near the site of the current cathedral. In 1850 Father Marin bought the land at the mouth of the Khlong Damnoen Saduak and donated it to the church. In 1890
