The Cathedral Parish of St. Patrick is the seat of the Diocese of El Paso and the mother church for 686,000 Catholics.

•  Plans to build the church of St. Patrick originated with the Irish Catholic community in El Paso in 1908 when parishioners at Holy Family Church (formerly St. Mary Chapel) began to fundraise for a larger church.
• Several sites were considered for the new church before Father Edward Barry, S.J., the pastor at Immaculate Conception, settled on the corner of Mesa and Arizona Streets which he bought in February 1914 for $20,000.
•  The church was designed by Barnett, Haynes and Barnett of St. Louis in the Byzantine style of architecture and constructed from brick and carrara marble.
• Designed to seat 720 worshippers, the interior is modified byzantine with the woodwork of golden oak and the floor of polished oak. The interior is adorned with Roman columns, elaborate frescoes that depict biblical scenes, and the Stations of the Cross that are carved in bas-relief on the interior walls. The impressive marble altar, 75 feet tall, is a duplicate of the altar in the St. Louis Cathedral and contains an eight-foot statue of the Sacred Heart of Jesus under a large canopy that is topped with a golden eagle.
• On November 19, 1917, the finished St. Patrick Church was officially designated by Bishop Schuler as the Cathedral for the Diocese of El Paso. The dedication ceremony took place on Thanksgiving Day, November 29, 1917.
