Clifton Observatory, Bristol

Clifton Observatory is a circular stone tower on Clifton Down that contains a working camera obscura inside. The structure offers viewpoints across Bristol, the Avon Gorge, and Clifton Suspension Bridge.

The building was constructed in 1766 as a corn mill until a fire left it unused. Artist William West transformed it into an observatory in 1828.

The tower houses a working camera obscura, a rare device that uses light and shadow to project the city onto a screen inside. Visitors experience Bristol through this Victorian technique, creating a meditative way to see the city.

The tower is accessible on foot from Clifton Down, though the stairs can be challenging depending on fitness level. The visit typically combines the tower, cave, and camera obscura in one location.

A tunnel around 200 meters long connects the tower to Giant's Cave and ends at a window carved into the cliff face, sitting 250 meters above the Avon Gorge. This underground passage was once a natural cave channel that was later adapted for visitors.
