About

Clifton Observatory, located on Clifton Down atop the Avon Gorge, offers unforgettable views of Clifton Suspension Bridge and the surrounding area. A historic site with a fascinating past, Clifton Observatory offers unique tourist attractions, including one of the only working Camera Obscuras open to the public in the UK, and access to the legendary Giant’s Cave.

Built on the site of a Celtic Iron-Age fort, the Observatory was originally constructed as a snuff mill in 1766. The mill was later leased by William West, a photography and engineering enthusiast who was a member of the Bristol School of artists. West saw the potential in the ‘picturesque ruin’ and converted it into an Observatory. He installed several telescopes and a range of other astronomical resources and instruments, including the Camera Obscura.

The Camera Obscura offers a unique view of the Clifton Suspension Bridge and Avon Gorge. From a dark room atop the tower, visitors can experience what is sometimes nicknamed ‘Victorian CCTV’ – a remarkable feat of Victorian engineering which still fascinates and astonishes people to this day, almost two centuries later.

During his time at Clifton Observatory, West also pioneered the excavation of an underground passageway to the Giant’s Cave, which was originally only accessible via the sheer and dangerous cliff-face. Now visitors can adventure down 130 steps through the rocks to the Cave, where spectacular views and the legendary giants wait.

The attractions at Clifton Observatory host seasonal trails during school holidays for kids, including the Giants’ Easter Hunt, a Halloween Trail, and a Christmas Elf Hunt.

Clifton Observatory also houses a café with indoor and outdoor seating and a range of locally-sourced refreshments, along with a spectacular rooftop terrace where visitors can enjoy breathtaking panoramic views – the best in the city.

Please note that Clifton Observatory and the 360 café are accessible by foot only and that the attractions are not wheel-chair accessible. Children must be 4 or older to visit the Giant’s Cave and the Cave is not suitable for those with claustrophobia, mobility issues, or sight problems. Dogs are welcome in the Camera Obscura, the rooftop terrace, and the café, but not the Cave.
