1. Once the Site of Cathedral School Marker
This site was once the home of the Cathedral Grade School. The building was designed by renowned Denver architect Frank Edbrooke in the Classic Romanesque style. It was built in 1891, suffered a devastating fire in 1955, and was completely remodeled including a high school addition. It stood proudly until its closing in 1965, and its demolition by the archdiocese in 2006. Hundreds of children attended the school and walked the stage as high school graduates. The current structure is a nod to the beautiful architecture and colorful history that continues to make Uptown Denver the most authentic neighborhood in the city.

(by Thomas J. Noel) Excerpt: Frank E. Edbrooke (18411921), Colorados best-known and most-celebrated architect, designed more than seventy buildings, including many now-landmarked structures that helped define Denvers built environment. He gave the city its first fine commercial buildings while also designing institutional and domestic architecture. Edbrooke introduced new styles and techniques to the city, from the steel-frame, Richardsonian Romanesquestyle Brown Palace Hotel (1892) to his own Queen Anneinspired residence at 931 East 17th Avenue (1889).(Submitted on December 4, 2025, by Cosmos Mariner of Cape Canaveral, Florida.)
Edbrooke became Colorados premier architect of the late nineteenth century and early twentieth. He was a founding member of the Colorado chapter of the American Institute of Architects, and hisarchitectural firm, F. E. Edbrooke & Co., was the largest in the state. Edbrooke used local red sandstone, granite, and brick to create massive yet graceful Richardsonian Romanesque structures.
