After this week’s devastating fire at the Notre Dame Cathedral in Paris, it seems like an appropriate time to appreciate our own masterpiece of religious architecture. Designed by famed French architect Emmanuel Masqueray, the Cathedral of St. Paul held its first mass in 1915 after eight years of construction. Although the exterior structure was complete, it would take another couple of decades to finish the interior. But Masqueray, whose work also includes the Basilica of St. Mary in Minneapolis, didn’t live to see it completed. He died in St. Paul in 1917. This series of images from the Pioneer Press photo archive illustrates the construction of the Cathedral’s exterior structure from 1907 through 1914.
