Avery House stands as a notable Victorian residence in Fort Collins, Colorado, constructed in 1879 during the city's formative years as a frontier settlement in the Arkansas River valley. The structure was built as a family home for William Avery and his household during a period of significant architectural development in northern Colorado, when wealthy merchants and settlers were establishing substantial residences that reflected their social standing and economic prosperity. The house was recognized for its architectural merit and historical significance, eventually receiving designation as a National Historic Landmark, acknowledging its importance to the cultural heritage of the region and its representation of Victorian-era domestic architecture. The household experienced devastating tragedy in the 1880s when a female member of the family, identified as Emily, perished in a catastrophic fire that engulfed portions of the residence. The circumstances surrounding Emily's death remain a point of historical interest, as the fire resulted in her becoming trapped within the upper rooms of the house, unable to escape the rapidly spreading flames. The loss marked the home with profound sorrow, as it represented the violent and sudden loss of a young life in an era when such domestic disasters were both common and catastrophically fatal. Fire, an ever-present danger in homes heated by wood and lit by open flame and candles, claimed numerous lives throughout the nineteenth century, and Emily's death joined countless others in the grim statistics of domestic tragedy. Following Emily's tragic death, William Avery himself passed away in 1890, and the circumstances that followed added further dimensions of mystery to the property's history. His widow remarried merely twelve days after his death, an unusually swift union that prompted considerable contemporary suspicion and contributed to the house's dark reputation among neighbors and community members. The rapid remarriage raised questions about the widow's emotional state and motivations, fueling rumors and speculation that have persisted through generations, adding layers of intrigue to the property's historical narrative. Those who have reported experiences within Avery House have described encounters consistent with the presence of distressed spiritual entities rooted in the tragedies the house witnessed. The middle bedroom located upstairs has emerged as a focal point for paranormal activity, with visitors and observers reporting the apparition of what is believed to be an unhappy child spirit, likely connected to the tragic death of Emily. Cold spots have been documented in various upstairs rooms, accompanied by unexplained sounds including footsteps, creaking floorboards, and disembodied voices that seem to originate from empty spaces. The intensity of reported activity varies, with some accounts describing vivid apparitions and sustained phenomena, while other visitors experience only subtle manifestations of presence, suggesting variation in either the strength of the entities or the sensitivity of individual visitors. In its modern incarnation, Avery House operates as a historic house museum open to the public on Saturday and Sunday afternoons from 1 to 4 p.m., operated by Poudre Landmarks, a preservation organization dedicated to maintaining the cultural and architectural heritage of Fort Collins. The house welcomes visitors interested in both the architectural history of the Victorian era and the documented paranormal phenomena associated with the property. Documentation from docents and staff members presents varying accounts of paranormal activity, with some reporting no substantiated supernatural encounters during their tenure, while others and visiting researchers have documented unexplained phenomena in the parlor, pantry, and upper bedrooms. The house remains a subject of ongoing historical and paranormal interest within the regional community, attracting both heritage enthusiasts and paranormal investigators who seek to understand the spiritual legacy of the tragic events that unfolded within its walls.

The Holiday Inn Holidome in Fort Collins, Colorado presents a distinctive intersection of twentieth-century American hospitality architecture, family leisure culture, and reported paranormal phenomena that has made the property notable in both regional hotel history and paranormal circles. The Holidome concept itself—an enclosed, climate-controlled recreational facility combining indoor swimming pools, hot tubs, and recreational amenities—represented a particular approach to mid-twentieth-century hospitality design, one that sought to provide year-round family vacation experiences regardless of external weather conditions. The Holiday Inn chain's Holidome properties, developed in the 1970s and 1980s, were positioned as premium family vacation destinations, offering facilities and amenities designed to entertain guests across multiple generations. The Fort Collins location, also known as the Plaza Hotel during certain periods of its operational history, served as a regional hospitality landmark, catering to families, business travelers, and tourists visiting the northern Colorado region. The physical structure of the building, with its multiple wings, numerous guest rooms, and extensive recreational facilities, created an environment designed to facilitate extended family stays and provide varied experiences within a self-contained environment. The transition from conventional hotel operations to its present status as a documented paranormal location reflects a pattern sometimes observed at hospitality venues—the accumulation of unusual events and phenomena that eventually prompt broader recognition of a location as potentially haunted or spiritually active. Guest reports of unusual occurrences at the Holiday Inn Holidome began to accumulate over the years, creating a body of anecdotal evidence that eventually attracted the attention of paranormal investigators and paranormal enthusiasts. These reports, rather than remaining isolated incidents dismissed as coincidence or misperception, formed a coherent pattern suggesting something more systematic occurring at the location. The consistency of certain types of reports across different time periods, different guests, and different areas of the property suggested to many observers that the phenomena were not random or isolated but indicative of genuine paranormal presence. The property's history of guest experiences eventually led to its recognition as one of northern Colorado's most actively reported haunted locations. The paranormal activity reported at the Holiday Inn Holidome clusters around several distinct entities or manifestations, each with its own apparent personality, location, and type of phenomena. One of the most frequently documented manifestations involves a small child, typically described as a young girl, who appears to display mischievous characteristics rather than threatening or malevolent tendencies. This entity is characterized as playful, engaging in tricks and pranks throughout the property, with reported incidents including movement of objects, manipulation of doors, and other poltergeist-like activities that suggest an entity engaged in attention-seeking behavior rather than hostile manifestation. The child entity is often reported in specific guest rooms, particularly in a king suite and a room across the hall, suggesting that the child's presence may be connected to a tragic incident involving a child that occurred at the location. A second documented presence is described as a male ghost characterized by an ominous or threatening quality, reportedly concentrated in the northwest wing of the property. This entity is described as possessing a heavy, oppressive presence—witnesses report feeling dread, unease, and a sensation of being threatened when in close proximity to where this manifestation is active. A third documented presence is described as a female ghost reportedly observed peering from windows or looking out toward the exterior of the property, suggesting a consciousness oriented toward the outside world or potentially watching for something or someone. The specific phenomena associated with these entities include cold spots that manifest suddenly in particular areas of the property, often concentrated in rooms or hallways associated with reported apparition sightings. Doors throughout the building reportedly open and close without human intervention, sometimes with significant force, while other objects move without apparent cause. Guest reports describe arriving at locked doors that open inexplicably, items displaced from their original positions, and the sensation of presence in empty rooms. Some accounts suggest purposeful interaction—phenomena that appear responsive to guest behavior, questions, or emotional states, suggesting intelligent manifestation rather than mere residual haunting. The swimming pool area, despite being designed as a family recreational space, is frequently cited in reports of unusual coldness and unexplained sounds, leading some guests to report discomfort and reluctance to use these facilities during certain times of day. The cumulative effect of these phenomena has established the Holiday Inn Holidome as a location of particular interest to paranormal researchers and paranormal tourists. The property's dual nature—a conventional hospitality business still operating to serve guests while simultaneously functioning as an active paranormal site—creates a unique dynamic in which visitors may be family vacation tourists, paranormal investigators, or both simultaneously. Some guests have reported deliberately selecting the property specifically to investigate or experience its paranormal reputation, while others have been surprised to encounter phenomena during what they believed would be routine hotel stays. The property has been featured in paranormal television programs and paranormal investigation documentaries, bringing broader awareness to its status as a actively haunted location. Management and staff responses to paranormal activity vary, with some acknowledging guest reports while others maintain a more skeptical stance toward the phenomena. This intersection of conventional hospitality operations and actively reported paranormal phenomena continues to make the Holiday Inn Holidome a distinctive location in American paranormal geography.
