Puebloans have enjoyed the Mineral Palace Park for decades, but many may not know its colorful history and grandiose beginnings.You Should’ve Seen It: Pueblo’s Mineral Palace follows the strange and little-known history of the Colorado Mineral Palace, which despite being an icon of the state and the city in the first half of the twentieth century, drifted into urban legend and folklore in the second half. Museum curators have assembled oral histories, artifacts, archival documents, historic photographs, newspaper clippings, and more to tell the story of a palace built to showcase Colorado’s mineral riches. The exhibit opens on Friday, September 9 at History Colorado’s El Pueblo History Museum and will be housed in the museum’s International Hall. Locals will be pleased to learn that the beloved jeweled miniature of the Mineral Palace made by Carlos Otero is returning to El Pueblo History Museum after spending a few years at the History Colorado Center as part of the Zoom In exhibit.
