Herschel Observatory at Prior Park College
Ralph Allen Drive , Bath, Avon, BA2 5AH, South West England
The Prior Park College Observatory is a recent (2024) addition to Bath’s storied astronomical heritage. Located at the edge of the private school’s playing fields, the observatory sits within a sleek Pulsar Dome, just under three metres in height, carefully positioned for optimal viewing.
The Observatory is 2.7m in diameter and contains a 10″ Meade LX200. As the observatory is located on the edge of a cricket pitch, it has its own movable cage and net to avoid it being a target for ambitious batsmen!
The site was selected by Simon Holbeche of Bath Astronomers, ensuring an ideal location for celestial observation. The facility not only supports the school’s science curriculum but also serves the local community, offering a range of inclusive activities and events in partnership with Bath Astronomers.
