Assumption Cathedral

Assumption Cathedral is the principal Roman Catholic cathedral in Thailand, located on Charoen Krung Road in Bang Rak, Bangkok, near the Chao Phraya River. Built originally in 1821 and rebuilt in Romanesque style between 1919 and 1922, it serves as the seat of the Archdiocese of Bangkok. Notable for its red-brick exterior, twin towers, stained glass and imported marble interior, it is a historic landmark of the Bang Rak riverside community.

Visitors can expect a red-brick Romanesque cathedral with twin bell towers, arched windows and a rectangular nave set back from Charoen Krung Road. Inside is a high vaulted ceiling, marble altars, stained-glass windows, statues and religious artwork. The compound includes a courtyard, grotto and adjacent Assumption College buildings. The setting is urban and riverside, close to the Mandarin Oriental Hotel and the Chao Phraya River. Visitors can explore the interior outside Mass times, take photographs and attend services.

The original church was built in 1821 by French missionary Father Pascal during the reign of King Rama II to serve the local Catholic community. The present Romanesque structure was rebuilt between 1919 and 1922 under architect Ercole Manfredi during the tenure of Father Colombet, using imported materials including marble from France. It was consecrated in 1922 and has served continuously as the cathedral of the Archdiocese of Bangkok.

As the principal Catholic cathedral in Thailand and seat of the Archdiocese of Bangkok, it is the center of Roman Catholic religious life in the country. It reflects the long-standing French missionary presence and Catholic community in the Bang Rak riverside area and is an important example of Western ecclesiastical architecture in Bangkok, visited for religious services, weddings and cultural heritage interest.
