Winchester Science Centre & Planetarium, Planetarium

About Venue

Winchester Science Centre & Planetarium is a large-scale, experience-led event venue just outside Winchester that brings science, imagination, and a real sense of wonder into every gathering. This is a venue people remember, not just because of its size or setting, but because it feels genuinely different, playful, and sparks curiosity within adults and children alike.

The venue is particularly well suited to host conferences, brand launches, drinks receptions, gala dinners, award ceremonies, and end of year celebrations where you want guests to feel engaged from the moment they arrive. It works brilliantly for organisations looking to host something bold, memorable and full of surprises.

What really sets this venue apart is the support behind the scenes. The on-site team are experienced, friendly, and very used to helping organisers bring ambitious ideas to life. Exclusive hire options and premium touches make it easy to create a VIP feel, while flexible catering arrangements allow events to be tailored without feeling restricted. For planners, this means less stress, smoother logistics, and a space that adapts to your vision rather than the other way around.

About this space:

The Planetarium is a purpose-built, theatre-style event space for up to 168 guests within Winchester Science Centre & Planetarium, designed for high-impact presentations, film screenings, and immersive launches. The room centres around a full 360° digital projection dome, creating a fully enclosed visual environment that keeps audiences focused and engaged from start to finish.

This space feels dramatic and technical rather than decorative, making it particularly well suited to conferences, product reveals, award ceremonies, and film or content screenings. Fixed tiered seating ensures clear sightlines to both the dome and the small stage, while integrated sound, lighting, and presentation systems support professional production standards. The controlled lighting and acoustics make it easy to manage large audiences without distraction, and the space works especially well as a main plenary room within a wider event.

Elevate your event by adding a full‑dome planetarium show that truly wows your guests. Guided live by our expert science Inspirers, this immersive experience takes audiences on a breath-taking journey through the solar system, delivering inspiring science and unforgettable visuals. A truly unique addition to any corporate event.
