Brief History Overview
Julie and Spencer Penrose
Julie and Spencer Penrose married in 1906 and spent their life in Colorado Springs building and giving back to the community. The couple created many longstanding attractions in the Pikes Peak region, including the highway up to Pikes Peak and The Broadmoor hotel. In 1926, Spencer established Cheyenne Mountain Zoo.




Zoo founding in 1926
Spencer began collecting exotic animals in the early-1910s, and by 1926 hoofstock pens lined Cheyenne Mountain Highway, which he had constructed the year before. The Zoo grew rapidly over the next several years as Spencer built exhibits for his expanding animal collection. After personally funding the Zoo for more than a decade, Spencer incorporated Cheyenne Mountain Zoo as a nonprofit in 1938, establishing a legacy in which the Zoo continues to be privately funded to this day.
