15 Best Historical Landmarks in Denver

Daniels & Fisher is a historic Denver landmark centered on an elegant clock tower with strong architectural character and sweeping city views. Self-guided access takes visitors upward by elevator to viewing areas near the top, where the skyline, Rocky Mountains and the tower’s clock details become part of the visit.

The Governor’s Residence at the Boettcher Mansion is a Denver historical landmark known as Colorado’s Home. Built as a private residence in 1908, the elegant house later became a setting for governors, official functions and public tours. Ornate interiors, chandeliers, period furnishings, gardens, a rose garden and a solarium give the visit a strong sense of place.

Tower of Memories is a distinctive Denver historical landmark: a seven-story mausoleum built in 1929 with marble interiors, historic photographs and a striking exterior façade. The quiet, reflective setting offers an unusual way to encounter local history and memorial architecture, while upper levels can provide elevated views when access is available.

Westminster Castle is a dramatic Denver-area historical landmark built in 1893 from sandstone associated with Red Rocks. Set high above the city, the castle combines a striking stone exterior with broad views toward Denver and the mountains, creating a memorable architectural stop even when viewed from outside.

Atop Denver’s historic Daniels & Fisher building, Clock Tower Events turns a landmark into an extraordinary setting for weddings, proposals, date nights, elopements, and other celebrations. Five distinctive floors connect by staircases, with two wrap-around balconies, panoramic views of the city and surrounding mountains, and the original clock faces still ticking.

The venue feels spacious without becoming overwhelming, giving each level its own character and creating a natural flow for ceremonies, dining, dancing, and photography. A romantic table can be arranged in front of the clock faces or on the 20th floor for intimate occasions. Event planning is handled with attentive, communicative support, including help with tours, catering coordination, and bar arrangements. Popular items such as ribs and brisket are best treated as limited-availability choices when planning catered events.

The Equitable Building has anchored Denver’s Central Business District since 1892, combining a dignified granite, brick, and terra-cotta exterior with one of the city’s most memorable interiors.

Fleming Mansion brings Denver’s civic history into an intimate event setting. Built in 1882 as the mayoral home of James Fleming, it later served as City Hall for the City of South Denver before that community became part of Denver. Historic detailing gives the rooms a distinctive character, while the scale works well for gatherings that want atmosphere without losing room for dining, music, or dancing.

The Denver Mile High Steps Marker is a compact historical landmark on the Colorado State Capitol steps, marking the point exactly one mile above sea level. It is easy to find, free to visit, and well suited to a quick downtown stop, family walk, or photo opportunity.

The marker works best as a brief addition to a Capitol-area outing rather than a standalone extended visit.

Built in 1891, the Kittredge Building brings recognizable historic architecture to Denver’s 16th Street Mall.

Smedley House at 9th Street is a quietly compelling Denver historical landmark, valued for the stories connected to nearly 150 years of local and American history.
