English: Built in 1904-07, this Renaissance Revival and Baroque Revival-style cathedral was designed by George I. Lovatt Sr. to replace the earlier St. Patrick Catholic Church, was was built on the same site to serve a primarily Irish-American Catholic community in 1826, which had become the Pro-Cathedral of the Diocese of Harrisburg upon its formation in 1868. The previous church was a Gothic Revival-style structure that had been altered and extended during the 19th Century, with a central open belfry, cross-gable roof on the front wing, and a long sanctuary to the rear, only occupying a relatively small portion of the lot, with the rest being home to a graveyard. The construction of the present Cathedral necessitated the demolition of the previous church and the relocation of remains in the surrounding graveyard to Mount Calvary Cemetery, a process that was completed by the time ground was broken for the Cathedral in 1904. The building features two front towers with small undersized belfries that replaced the original open stone belfries, which were larger but were removed at some point during the 20th Century, a large copper-clad dome with a lantern featuring ionic pilasters and arched windows, oxeye windows, a decorative simple cornice, a lantern with open archways and ionic pilasters with a bell-shaped cap and cross on top, a limestone-clad exterior on the rest of the church, a portico on the second floor of the front facade with a pediment, ionic engaged columns, two blind arched flanking a central arched stained glass window, and a circular attic vent in the pediment, a cornice with dentils, a stone cross atop the front pediment, entrance doors with doric porticoes, with triangular pediments on the doors at the bases of the towers and an arched pediment at the central entry door portico, decorative wood panel double doors, stone quoins, a latin cross layout with doric pilasters and circular stained glass windows on the side gable ends, doric pilasters on the side facades of the aisles between the building’s roman arched stained glass windows, arched windows above the shed roofs of the aisles on the nave a semi-circular rear apse, and a landscaped courtyard between the church and an adjacent 19th Century Italianate-style townhouse. Inside, the church is beautifully decorated with corinthian columns, stained glass windows, a barrel vaulted nave, decorative cornices with brackets, decorative trim, a marble floor, wall and dome frescoes, shrines, and an ornate altar. The cathedral continues to serve as the seat of the Diocese of Harrisburg, and is a contributing structure in the Harrisburg Historic District, listed on the National Register of Historic Places in 1976.
