Stretching back to 1884 and the construction of Holy Guardian Angels Pro Cathedral School, an educational enterprise has operated continuously on the current Cathedral High School campus. At times throughout the past century the school operated grades #1 through #12. Throughout most of the 1960s Cathedral operated only grades #9 through #12, but then again in 1971 it added grades #7 and #8. Cathedral High School was separately incorporated from the grade school and from Holy Angels (Cathedral) Parish in 1945. The school’s mission, inspired and informed by Catholic tradition, has always been to educate people while inspiring them to virtuous lives.
1875 – The Northern Vicariate, forerunner of the Diocese of St. Cloud, is established with Benedictine Abbot Rupert Seidenbusch, OSB appointed first Bishop. The Cathedral of the Diocese is established with the purchase of the Broker home on 6th Avenue and 4th Street overlooking the Mississippi River to the East. Bishop Rupert prevailed upon his confreres to make St. Mary’s – several blocks to the Southwest – the Cathedral but the monks chose to keep St. Mary’s as a Benedictine Church, thus the necessary creation of Holy Angels.
1884 – Bishop Rupert Seidenbush, OSB opens a school as part of the Holy Angels Pro Cathedral Parish. This was coincidentally the same year as the Baltimore Declaration.
1887 – A three-story grade school building is constructed on the northeast corner of the 200 Block between 6th and 7th Avenues North; it later houses the high school on its 3rd floor and still later becomes known and used as the Vocational Building in the 1960s.
1890 – A Pro Cathedral Rectory/ Chancery is constructed immediately adjacent to the Broker home which ultimately serves a dozen or more functions and occupants until its demolition due to neglect and disrepair in 2009.
