A VIVID experience of light and colour is the latest attraction at Stockton International Riverside Festival.

Visitors to the largest inflatable structure to ever come to Teesside walk inside the brightly-coloured cathedral to experience the stimulating environment of stained plastic windows, arches and domes.

Trips to the enchanting kaleidoscope can also leave the visitor relaxed as they sit or stand in the cushioned tunnels and soak up the ever-changing hues lit by the outside. Similar structures, called luminarium, have been used to provide sensory stimulation for people with cerebral palsy.

The unusual attraction is set up by the Architects of the Air and called the Archipelago.

Archipelago Manager Jane Pitt said: "It is a beautiful experience, creating an atmosphere that can be either stimulating or relaxing. The environment is a combination of air, colour and space, which is ever changing with natural light from outside. There is no light inside.

"The designer, Alan Parkinson, has created other similar interactive sculptures based on his fascination with light, colour and form, and they have been used for disabled people who need to be stimulated through their senses, and experienced in a safe, soft play environment."

Archipelago is at the ruined church site of Holy Trinity, Stockton, until Sunday, and is open from 2pm to 8pm, on weekdays and midday to 8pm at the weekend. Entry is £2.50.
