The National Museum of Wales in Cardiff, established in 1907, is housed in a grand Edwardian building in the city’s civic center. It officially opened to the public in 1927, showcasing Welsh art, natural history, and archaeological artifacts. The museum’s collections have grown significantly over the decades, with notable expansions in the 1960s and 1990s.

Paranormal activity has been reported at the museum for many years. Staff and visitors have described unexplained phenomena, particularly in the museum’s older sections. One persistent ghost story involves the spirit of a former caretaker who is said to still roam the building’s corridors at night. Witnesses have reported hearing footsteps and seeing a shadowy figure in areas that should be empty after hours.

Another frequently cited ghostly encounter involves a young woman in Victorian-era dress, often seen near the museum’s art galleries. Some believe she may be connected to one of the portraits on display, though her identity remains a mystery.

In the natural history section, there have been accounts of exhibit animals appearing to move or change position when no one is looking. Staff members have reported feeling watched or sensing an unseen presence while working alone in this area.

The museum’s basement storage areas have also been the subject of paranormal claims. Employees working in these spaces have described sudden temperature drops, unexplained noises, and objects seemingly moving on their own.

During World War II, the museum was used to store valuable artifacts from other institutions for safekeeping. Some speculate that this period may have contributed to the building’s supernatural reputation, with stories of wartime spirits and residual energy from that tumultuous era.
