For more monochrome madness, visit Dragonstar's Weekend in Black and White.
Thanks to Dianne of Adelaide and Beyond for telling me where to find this architectural gem.
The Pilgrim Uniting Church was dedicated in 1867 as the Stow Memorial Congregationsal Church, named for he First Congregational Minister, Thomas Quinton Stow, who arrived in the Colony in 1837 and commenced the first Congregational services in South Australia. It became the Pilgrim Uniting Church in 1975 after the amalgamation of the Methodist and Congregational Churches to form the Uniting Church.
The church is an example of "Revival Gothic" architecture which is quite rare in South Australia.
