Known as the "Westminster Abbey of the Pacific," Kawaiahao Church was the first Christian Church built on Oahu. Dedicated on July 21, 1842, “The Great Stone Church” is made of 14,000 coral slabs from ocean reefs that were hauled from the sea by native laborers and missionaries. The church and the grounds were named a National Historic Landmark in 1962. https://www.gohawaii.com/islands/oahu/regions/honolulu/kawaiahao-church

Seat of the archdiocese of Nouméa since 1966, Saint Joseph’s Roman Catholic cathedral was built between 1887 and 1897 by a penitentiary workforce and following the construction plans of a former convict named Labulle. Consecrated in 1890, before the end of its construction, the cathedral is laid out as a 56-meter-long Latin cross, with a 36-meter-large transept. 15.5 meters high, the building's south west facade presents two 25-meter-high towers on both sides of the porch. Both towers, the buttresses and the bay frames are made of cut stone, the other walls are made of lime-rendered rubble stone. https://www.newcaledonia.travel/au/noumea/saint-josephs-cathedral

The original Cathedral for the Archdiocese of Canberra Goulburn is now referred to as Saints Peter and Paul's Old Cathedral. Recognised by the National Trust of Australia the former Cathedral and Bishop's House are significant items of the city's cultural and architectural heritage. Several types of stone were used in the Cathedral's construction. The most significant of these was diorite porphyrite, a very hard green stone from a quarry on the Bungonia Road. The use of the green porphyry stone makes this the only Greenstone Cathedral in the world. https://www.visitnsw.com/destinations/country-nsw/goulburn-area/goulburn/attractions/saints-peter-and-pauls-old-cathedral

The stunning belltower, soaring windows and massive stone work are the first impressions one has of St Saviour's.
