In 1904 they were commissioned to design the Roman Catholic Cathedral of St James in Seattle by Bishop Edward J. O’Dea, whose diocese had purchased property on Seattle’s First Hill and demanded a cathedral “that must surpass anything in the West.” The Italian quattrocento design features tall, paired campanili at the west end and a central dome. The firm sent two young architects, W. Marbury Somervell and Joseph S. Coté, to oversee construction on the site, who went on to establish a thriving architectural practice in Seattle. The cornerstone ceremony took place on November 12, 1905. The cathedral was completed in 1907 and solemnly dedicated on December 22, 1907. Unhappily, under the weight of two feet of wet snow the dome collapsed on the afternoon of February 2, 1916, dropping 400 tons of masonry eighty feet into the empty cathedral, shattering every window and leaving a gaping hole that exposed it to the elements. The cathedral reopened on March 18, 1917, but with a flat roof over the crossing. The central repositioning of the altar in response to reforms of the Second Vatican Council has finally brought it into the position envisaged by the architects.
