This elegant 3-story building features a large center courtyard connecting the former Cathedral High School on the north to the former rectory on the south. The courtyard is enclosed by an arched cloister to the east and a decorative stucco and wrought iron wall to the west. Original wood windows and terra cotta elements as well as a four story bell tower characterize the finely detailed exterior aspects of the building. Both the interior and exterior of the building possess a high level of architectural integrity; however an addition to the school portion of the building was constructed by the early 1950s. The addition was designed to match the Spanish Renaissance Revival style of the original construction.

The building also features a red clay tile roof and original arched wood doors. Although the wood windows and doors are deteriorated by weather and some cracking in the stucco is evident, the building is in very good condition. An ogee arch marks the main entrance to the convent on the west façade of the south building. A prominent religious statue resides in a niche above this entrance. The windows are predominately casement leaded lights on the first floor and follow a pattern found in renaissance revival styles where hierarchy allow for different sizes and shapes of windows to mark each floor respectively. Double hung rectangular windows are on the second floor and Roman arch top windows are on the third floor of the convent (south building). The original Cathedral High School (north building) has regularly patterned double hung windows with highly decorative lintel panels above and Moorish inspired scrolled pilasters marking each side of the masonry opening and some corners. Leaded lights are in the bay section on the north façade and in the courtyard.

The roof is bracketed at its eaves and is predominately hipped with gabled protrusions on the Cathedral High School. The 1950s addition has a tiled mansard roof masking the flat roof behind. The skin of the building is covered in painted smooth stucco. A few decorative cartouches are located in the courtyard with cruciform symbols. The open arcades of the second floor cloisters are decorated with trefoil arches, chamfered columns and Greek cross forms inset within round medallions. The first floor arcade is open on the east with Romanesque forms and in-filled with windows on the south. Highly decorative plaster on the walls and ceilings of the interior accentuate window and door openings, as well as reinforce the Renaissance Revival style groin vaults in the hallways and chapel.

The building has reinforced concrete floors and staircases, and is of fireproof construction throughout. In addition to the new construction of the convent, the building that had been used as a rectory at 1854 Grant, as well as the nearby two-story barn, were transformed in 1921. Construction was handled by Charles J. Dunn, a local contractor, at a total cost of $135,000. Dunn was a prominent citizen responsible for a large amount of the construction in Denver during the late 19th century. Dunn, a resident of Denver since 1887, was a general carpenter and builder with many contracts for private and public buildings. In addition to the construction business, he was also vice-president of the Joseph P. Dunn Leather Company, charter member and secretary of the Carpenters and Builders’ Association, member of the Knights of St. John, and Woodmen of the World, Denver, Camp No. 1.

Oscar Malo, Jr. Memorial Hall

History of Building:

1927 – Monsignor Hugh L. McMenamin started a campaign to build a gymnasium for the Cathedral High School, owned by the Denver Catholic Archdiocese.

December 3, 1928 – The cornerstone of the Oscar Malo, Jr. Memorial Hall was laid in front of the six hundred pupils of the school. The Oscar Malo, Jr. Memorial Hall was dedicated to Oscar and Edith Malo’s son, who died in 1921 from blood poisoning. The building was erected at a cost of $58,000, with the Malo family contributing $30,000.


The 1928 Oscar Malo, Jr. Memorial Hall was designed by famed architect Eugene Groves. To learn more about Eugene Groves, click HERE. The building is historically significant for its representation of the late Renaissance Revival architectural style in the City of Denver.

The Oscar Malo Memorial Hall was constructed in 1928 as a “modern” gymnasium and auditorium to serve the existing Cathedral High School and lower schools assembled on the block. The building is constructed out of red brick and cream terra cotta, featuring both neo-classical elements and linear, streamlined designs, more in keeping with the era of its design. The main entry is located on the east façade and features a low terra cotta arch surrounded by glazing that has since been replaced at an unknown time. The few windows that do exist are located on the north and east elevations and feature terra cotta sills. The parapet roof features a decorative terra cotta cornice with decorative terra cotta panels spaced around the perimeter of the parapet. The vast column free interior space is accomplished by steel trusses, and an original suspended walkway or track is hung above the ground floor. Although the original glazing has been replaced, the original openings are in tact and no additions to the building exist.


The Oscar Malo, Jr. Malo Memorial Hall is important for its association with noted philanthropists and prominent Denver citizens, Oscar and Edith Malo, and for its use as a state-of-the art gymnasium. When it was built, the gymnasium was one of the best equipped in the city, featuring a boxing ring, punching bags, complete facilities for basketball and volleyball, hanging ring and trapeze equipment.
In addition to being a training arena for athletes, the building was also used for plays, assemblies, diocesan conventions, dances, and other school activities. The building even had a complete apparatus for showing motion pictures, making the gymnasium an educational asset. Most recently the Memorial Hall was home to the “Original Scene,” a citywide youth theater company operated by Catholic Youth Services. Throughout its 83-year history the Memorial Hall has acted as a cultural hub, offering athletics for schoolchildren and dance and theater classes.

Preservation for a Changing Colorado

The 2017 update, Preservation for a Changing Colorado, resulted from a partnership between Colorado Preservation and History Colorado and Colorado Preservation, Inc. Prepared by Clarion Associates, the new report and accompanying website document the economic benefits of rehabilitation projects, analyzes property values and neighborhood stability in local historic districts, and summarizes the increasing impact of heritage tourism, private preservation development and the success of Colorado’s Main Street program. In a key finding, researchers found that for every $1 million spent on historic preservation in Colorado leads to $1.03 million in additional spending, 14 new jobs, and $636,700 in increased household incomes across the state! The 2017 report also considers the important role preservation plays in helping Coloradans provide new spaces for creative communities and co-working, create and sustain meaningful places, respond to the state’s changing demographics, and address climate concerns.
