Craig-y-Nos Country Park, located in the Brecon Beacons National Park in Powys, Wales, is a picturesque 40-acre parkland that was once part of the estate of Craig-y-Nos Castle. Featuring woodlands, meadows, and lakes, the park is a haven for wildlife and offers scenic walking trails, picnic areas, and a variety of flora and fauna. Originally landscaped during the time of opera singer Adelina Patti, the park retains elements of its Victorian charm, including historic pathways and ornamental gardens. Today, it is a popular destination for nature lovers, families, and dog walkers, providing a peaceful retreat with stunning views of the surrounding mountains.

Craig-y-Nos Castle, built in 1841 in Powys, Wales, was originally a Victorian country house before being purchased in 1878 by world-famous opera singer Adelina Patti, who transformed it into a lavish retreat frequented by European royalty. She added the Patti Pavilion theatre, which still stands today, and lived there until her death in 1919. Following her passing, the castle served as a tuberculosis hospital from 1922 to the 1950s, later becoming a nursing home before falling into disrepair. Restored in recent decades, it now operates as a hotel and wedding venue, also gaining a reputation for paranormal activity, with ghostly sightings—particularly of Adelina Patti—reported in the theatre and former hospital rooms.
