Sherwood Observatory Science Discovery Centre and Planetarium is a unique project that transformed a historic underground reservoir into a modern science and education facility. Located in Sutton-in-Ashfield in Nottinghamshire, the project combines heritage preservation with innovative design to create a space where visitors can explore science, astronomy, and technology.
Sherwood Observatory
Transforming Sherwood Observatory into a world-class facility featuring a state-of-the-art science and discovery centre and a new planetarium
Projects
Overview
Originally built in the 1880s, the Victorian reservoir once supplied drinking water to the local community. Over time, it was no longer needed, and the structure was left unused. Instead of allowing the building to deteriorate, the team at Sherwood Observatory saw an opportunity to reuse the historic structure in a meaningful way.
The project carefully preserved the original brick arches of the underground reservoir while constructing a new science centre above it. The design allows visitors to experience both the historic architecture and modern educational spaces in one location. The new facility includes interactive exhibition areas, classrooms for school groups, meeting spaces, and a café. One of the main attractions is the planetarium, where visitors can watch immersive shows about space and the universe.
The centre was developed to inspire interest in STEM subjects, science, technology, engineering, and mathematics, particularly among young people. Schools, families, and community groups can take part in workshops, educational visits, and planetarium presentations.
Today, the Sherwood Observatory Science Discovery Centre and Planetarium has become an important educational and community hub. Delivered by G F Tomlinson through the SCAPE Venture Framework, the project involved support from Ashfield District Council and used sustainable materials and energy-efficient systems, reflecting a commitment to environmental responsibility. High accessibility standards ensure that the observatory is welcoming to all, positioning it as a model of heritage-led regeneration to inspire learning and foster community growth.

“Right from the initial vision, this project has been about collaboration and teamwork. The new Planetarium & Science Centre has exceeded expectations and the excitement that has been generated in the area as it has taken shape has been tangible. We are really pleased to open our doors to visitors and show them the wonders of the universe.”
Dr Steve Wallace, Chairman of Sherwood Observatory and client project manager
