A church was built in 1886 on the same block on Fifth Street where the cathedral currently sits.[1] This church was replaced in 1910 with the present cathedral building.
The church was consecrated and elevated to the status of cathedral in 1951, when the Diocese of Juneau was created.[1][2]Robert Dermot O'Flanagan was appointed the first Bishop of Juneau, having served as a priest in Alaska since 1933.[3]
In 1962, the cathedral parish established a mission church in the Mendenhall Valley to serve the community in the Mendenhall Valley and around the Auke Bay area.[4] A decade later, in 1972, the mission church was separated from the cathedral parish by Francis Thomas Hurley and became St Paul the Apostle Parish.[4]
In 2019, fundraising began for a major renovation of the cathedral with support from Andrew E. Bellisario.[5][6]
