Throughout the latter half of the 19th century, the church and surrounding area played an important role for Christian missionaries arriving in Bangkok, particularly after 1860. The cathedral is part of a series of buildings which consist of
Assumption Convent School (Thailand), Catholic Mission of Bangkok, Assumption Printing Press and rectory which were inhabited by the missionaries during their time in the city.

The church has a relatively tall rectangular structure with a red brick exterior which stands out against its surrounding white buildings. The tall square towers flank the main entrance.

Chinese Teochew family business.

Crypt

The significant part of the cathedral is in the crypt underneath the Sanctuary, which kept the remains of the bishops and the missionaries, including that of Fr Nicholas Boonkerd Kitbamrung, who was proclaimed a martyr by Pope John Paul II on 5 March 2000 in the Vatican. His relics were transferred to the shrine built in the compound of St. Peter's church in Sampran, Nakornprathom Province. There still remains a special altar devoted to him on the left side of the cathedral.
Besides being a place of worship and for performing sacred ceremonies, the role of the Assumption Cathedral is the church of the head of the local diocese, which was led by Cardinal Michael Meechai Kitboonchu.
