Roman Catholic Archdiocese of Honiara The American development of Honiara as an army base and war depot turned Honiara into the new capital for the British Solomon Islands. The Catholic population tripled between 1947 and 1957, from 1000 to 3000. The first Holy Cross Church, built in 1947, was replaced by a much larger structure in 1957.

However, the Bellonese population significantly increased; they established permanent and semi-permanent houses in the Honiara vicinity, typically along the banks of the White River. The town was affected by creolisation.
