The Assumption Church, serving as the cathedral of the Singapore Diocese of the Russian Orthodox Church, is located in Singapore.

In 1990, the Resurrection Church of the Constantinople Patriarchate was established in Singapore, where services were conducted in English. However, Russian-speaking residents of Singapore, whose numbers gradually increased, sought to attend services in their native language. They approached the leadership of the Russian Orthodox Church with a request to send a priest and establish a parish.

From December 22 to 24, 2003, Metropolitan Cyril (Gundyaev) of Smolensk and Kaliningrad visited Singapore, serving as the chairman of the Department for External Church Relations. On December 23, he conducted the Divine Liturgy at the Armenian Church in honor of St. Gregory the Illuminator, attended by over eighty believers from Russia, Serbia, Hungary, Ukraine, Singapore, and other countries.

On July 12, 2007, Bishop Sergey (Chashin) of Ussuriysk arrived in Singapore and conducted a service at the Armenian Church of St. Gregory the Illuminator on the feast of the apostles Peter and Paul.

On October 12, 2007, the newly formed parish in honor of the Assumption of the Mother of God in Singapore was accepted into the jurisdiction of the Russian Orthodox Church. The Holy Synod entrusted the pastoral care of the parish to Bishop Sergey (Chashin) of Ussuriysk, vicar of the Vladivostok Diocese.

To conduct services, a small house was rented at the intersection of Dermawan and Remaja streets, near the Bukit Batok Nature Reserve, outside the city of Singapore. The building was in a dilapidated state, but thanks to the efforts of Bishop Sergey, three nuns, and a priest, it was restored. The first floor housed the domestic church and refectory, while the second floor provided accommodation for the clergy. An iconostasis, altar, and sacrificial table were installed, and church utensils were brought from Vladivostok. Regular services began on December 1, 2007. Initially, there were few parishioners, but over time their number increased. A Sunday school began operating in the church in August 2008. On December 12, 2008, the parish was registered with the Registry Office of Singapore and received official status as a religious organization.

According to Bishop Sergey, the parish established friendly relations with the parish of the Constantinople Patriarchate in Singapore. However, the Synod of the Constantinople Patriarchate expressed dissatisfaction with the emergence of a Russian Orthodox parish in Singapore.

On March 23, 2009, at the Patriarchal residence on Clean Lane, Patriarch Cyril met with Singapore's Minister of Foreign Affairs George Yeo, who promised to support the growing parish of the Russian Church in Singapore.

By 2011, services were held at least four times a week, with up to 200 people attending festive services. By then, the rented premises could not accommodate everyone. The Sunday school included groups for children aged 12-16 and 3-7 years.

In 2014, the parish moved to 110 Highland Road, closer to the center. The building had no signs indicating its affiliation with Orthodoxy. Priest Pitirim (Dondenko) explained in 2016: "We have no advertising or signs. We do not want to disturb the neighbors." The parish did not engage in active missionary work. Pitirim (Dondenko) emphasized: "Our goal is to meet the spiritual needs of the Russian community and all newcomers."

In May 2016, Singapore's Prime Minister Lee Hsien Loong, before his visit to Russia and participation in the Russia-ASEAN summit, expressed a desire to have a Russian Orthodox church in the country, noting that a site for a cultural center had already been chosen, which was agreed upon with the Russian side.

On February 10, 2017, Archbishop Sergey of Solnechnogorsk met with the Russian Ambassador to Singapore A. A. Tatarinov. They discussed further steps for implementing the project to build a Russian cultural center with an Orthodox church in Singapore.
