Endangered Places

Access the 2024 Endangered Places Nomination here

Since 1998, Colorado Preservation, Inc. has been working with communities throughout the state to save endangered historic buildings, landscapes, and archaeological sites through its Endangered Places Program.  

This program provides advocacy, awareness, and technical assistance to significant historic sites throughout Colorado that are in danger of being lost.  Colorado Preservation, Inc. devotes staff time and resources to rally concerned citizens and build local capacity so that listed as well as un-listed sites can be saved.  In 26 years, the Colorado’s Most Endangered Places program has highlighted 135 historic sites throughout the state; 55 sites have been SAVED and only eight have been lost. The program has a wide reach, with sites located in every region of the state in 49 of the 64 counties. 

Colorado’s Most Endangered Places are located throughout the state.  The general public is invited to visit, learn and be inspired!  Experience Colorado’s history firsthand by picking a region and taking a self-guided road trip.

This project is paid for in part by a
History Colorado State Historical Fund grant.

Meaning Behind the Categories of  Save, In Progress, Alert, and Lost

These categories are often site-specific as to what they actually constitute; however, generally, a “Save” constitutes that the historic resource is no longer endangered and threatened. This often means that one or more of the following have been completed:  rehabilitation, restoration, preservation, conservation, documentation, stabilization, or interpretation. When sites are ”In Progress” this means that they are currently in the process of the aforementioned; however, the work is not complete. “Alert” means that the Listed sites are still in the planning process to become a “Save,” and “Lost” means that the site has been demolished.

What We Have Learned…


Since the inception of the Endangered Places Program in 1997, Colorado Preservation, Inc. has only lost eight sites. While this is a good track record, with these losses there are important lessons to be learned. One of the biggest lessons we have learned is that community support is huge. How a site moves from “Alert” to a “Save” depends in great part on how involved and dedicated the community is to protect the resource. In recent years with the loss of the Given Institute in Aspen, and the Kit Carson Hotel, we have learned that it is best to be pro-active regarding advocacy and outreach on the benefits of preservation and historic resources in general. Over the years we have also learned the importance of engaging, educating, and empowering communities not only with the outcome of a particular listed endangered resource but also on how to prevent future threats.

Featured Project

Preservation for a Changing Colorado

Historic preservation has a direct economic benefit to communities and Colorado! Take a look at the 2017 study, which considered the ways adaption of historic places has a direct financial effect on the state.

This updated, most resent study, was the result of a partnership between Colorado Preservation, Inc and History Colorado, funded by a grant from History Colorado's State Historical Fund. Prepared by Clarion Associates, the new report 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 determined that for every $1 million spent on historic preservation in Colorado it produced $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, responds to the state’s changing demographics, and addresses climate concerns.
