Eighteen years after ground was broken, the new Roman Catholic Basilica of Philadelphia is dedicated
In Philadelphia, the city's bishop John Wood celebrated mass and the new Archbishop of Baltimore Martin John Spalding preached the sermon at the dedication of the new Cathedral Basilica of Saints Peter and Paul as the head church of the Roman Catholic Diocese of the city. Designed by Napoleon LeBrun, the structure had been begun in 1846 but the war had delayed its completion significantly. Philadelphia became an archdiocese in 1875 and the Basilica remains in use to this day on the east side of Logan Square. (By John Osborne)
