About
Catalyst Science Discovery Centre occupies one of Merseyside's most striking industrial buildings — the Gossage Building, a former soap factory on the banks of the River Mersey in Widnes. This remarkable Grade II listed structure was built for William Gossage, a pioneering Victorian chemist and industrialist, and has been transformed into an innovative science attraction that honours both its chemical heritage and the wider story of science and technology.
Established in 1987, Catalyst was one of the first dedicated science discovery centres in the United Kingdom, founded on the belief that science should be accessible, exciting, and relevant to everyone. The centre sits on the historic Mersey riverbank, with the river itself forming a dramatic backdrop and a constant reminder of the industrial waterway that helped make Cheshire and Merseyside the heartland of the British chemical industry for over a century.
The centre's four floors of interactive galleries explore a wide range of scientific themes, from the fundamental chemistry of everyday life to the industrial processes that underpin modern civilisation. Visitors can engage with hands-on experiments, interactive displays, and live demonstrations that bring scientific principles to life in memorable and accessible ways. The emphasis throughout is on learning through doing — encouraging curiosity, experimentation, and the kind of questioning spirit that drives scientific discovery.
The history of the chemical industry on Merseyside and in Cheshire is woven through the centre's displays, celebrating the industrial chemists and entrepreneurs who transformed raw materials into the products that defined modern life — from soap and alkali to pharmaceuticals and plastics. The Gossage Building itself is part of this story, a tangible link to the industrial revolution that reshaped the landscape and economy of north-west England.
A rooftop observation gallery offers panoramic views across the Mersey towards Liverpool and the Runcorn Bridge, providing a spectacular vantage point and a memorable experience for visitors of all ages. Catalyst is particularly popular with school groups and families, offering a rich programme of workshops, demonstrations, and curriculum-linked activities throughout the year.

💡 Visitor Tips
- Don't miss the rooftop observatory — the panoramic views across the Mersey towards Liverpool and the bridge are outstanding and put the industrial landscape into perspective.
- Check the daily demonstration timetable when you arrive and plan your visit around the live science shows — these are genuinely spectacular and not to be missed.
- Weekday term-time mornings are quietest. The centre is very popular with school groups, so weekend afternoons can be lively — perfect for children, but quieter visits are better in the morning.
- Free on-site parking makes driving the most convenient option. If using public transport, Widnes station is about a mile away; taxis are available at the station.
- Children can spend hours here — the interactive exhibits are genuinely engaging and the live demos are crowd-pleasers. Budget at least 3 hours for a family visit.
- Combine with a walk to Spike Island, just metres from the centre, for a remarkable industrial heritage landscape walk along the Mersey and Sankey Canal.
- The rooftop views and the Victorian architecture of the Gossage Building are photogenic. The glass lift ascending through the building is also worth photographing.
- The centre is fully accessible by wheelchair across all floors via lift. Pre-book if you require any specific assistance or a quiet-session visit.
