We are excited to see you at Doors Open Denver 2025! A well-loved portion of the Doors Open Denver festival, Open Sites allow for self-exploration at Denver’s icon sites, from historic buildings to new developments. All open sites are free to explore, and many feature tours and other activations to get to know the space better. This year’s Open Site activities will occur on Friday September 26 and Saturday September 27, and each site’s open dates and hours are noted on their site pages.
If a site has more information than what is found on their site page, you can find it below.
