Brown Palace Hotel
321 17th St.
Denver, CO 80202
(800) 627-7468

As one of the most historic hotels in the state, the Brown Palace Hotel is steeped in spooky legends and ghostly tales. Open since 1892, this iconic hotel has seen its fair share of presidents, movie stars and rock stars but the best stories come from the many encounters that the staff has had with resident spirits. One well-known story of the Brown Palace involves a heartbroken woman who had lived in room 904 in the hotel. When the hotel began to offer tours, the switchboard would receive calls from room 904, despite the fact that not a single phone was connected in the room. The scary stories at the Brown Palace are so popular that you can actually take a ghost tour of the hotel to get an insider look at the different phenomena.

Grant-Humphreys Mansion
770 Pennsylvania St.
Denver, CO 80203
(303) 894-2505

It may be one of the most beautiful homes in the city but the Grant-Humphreys Mansion is also home to many terrifying tales. This stunning home was built in 1902 and is the scene of a very suspicious death. Albert Humphreys died on the third floor of the home in a shooting accident, though some claim it was a suicide. In addition, the beautiful mansion is very close to Cheesman Park, another notoriously haunted location. Cheesman Park was originally City Cemetery, until Denver decided to move the cemetery in 1893. Like a scene out of a bad horror movie, crews only moved the tombstones leaving the bodies remained buried in the park. The proximity to the haunted cemetery and the mysterious passing of Albert Humphreys both contribute to the haunts at Grant-Humphreys Mansion.

Molly Brown House
1340 Pennsylvania St.
Denver, CO 80203
(303) 832-4092

As one of the most famous homes in Colorado, the Molly Brown House is open for tours year-round. This 1889 house was a home to Molly and James Joseph Brown in 1894. When their marriage ended in 1909, the home fell into disrepair. It has since been renovated and employees have said they have felt the spirits of Molly and James John in the home. The smell of pipe and cigar smoke has been found lingering in the halls and there are many cold spots throughout the house. Plus, there have been several sightings of a female apparition in Victorian dress who likes to rearrange the chairs at the dining room table. Is it Molly? Or perhaps another entity that calls this place home?

Union Station
Under construction through 2014
1701 Wynkoop St.
Denver, CO 80202

In 1881, this pink lava stone building was constructed to showcase the Union Depot and Railroad Company.  It’s always been a very busy place with more than 80 trains running through a day in the 1920s and 1930s and a fire in 1894.
It is reported that the ghost of a military officer haunts Union Station, specifically in the great hall. There have also been several sightings of apparitions on the train platforms and throughout the lobby areas, some of which have even tapped on the windows of the ticket booths. Though the sightings have not been as common recently, many swear their energy remains. Perhaps the military officer found his way home? Or maybe all the new construction has put an end to all the spooky happenings.

Denver City & County Building
1437 Bannock St.
Denver, CO 80202
(720) 865-7840

As the centerpiece of Civic Center Park, the Denver City & County Building is always busy and full of life and energy. It took nearly 26 years to complete the stunning piece of Denver architecture. Since 1900, there are records of reports of paranormal activity. On the second floor, a janitor and night-time watchman reported many spirits walking the hallways and an overbearing smell. It was so powerful that the two men reportedly quit their jobs and left the city. The building has gone through many renovations through the years, but there are often still reports of spirits wandering the second floor, though the smell has not been reported since.
