[1] Also known as St Olave's Danish Church, it was built in the early 19th century, when the area was part of Fredriksnagore – then a small (50 km²) colony of Denmark-Norway.

The building is now jointly controlled by the Church of North India (CNI) and Serampore College Council.

[2] A major restoration project there was rewarded by the 2016 UNESCO Asia Pacific Heritage Awards[3] The entrance has an open portico of twin columns under a broken-base pediment containing the royal monogram of Christian VII, king of Denmark when the church was consecrated.

One of the church bells is inscribed "FREDERICKS VÆRCK ANNO 1804", indicating it originated from a Danish factory.

The church is not particularly Scandinavian, but reflects the designs of contemporary churches in British India, in particular those in Calcutta, which were inspired by contemporaneous designs popular in Britain, such as St. Martin-in-the-Fields in London.
