A NEW exhibition is to transform the glasshouses at Keighley's Cliffe Castle.

The structure will be covered in photographic images produced by community organisations, using plant-based techniques.

Amongst those involved in the Photosynthesis project were Cliffe Castle Support Group, Keighley College, Highfield Community Centre, the Lion’s Den Shed and Keighley Healthy Living.

Working with Keighley Photo Hub director Lisa Holmes, participants learned how to make anthotypes – a heritage photographic process using just sunlight and eco-friendly solutions from different plants.

An event is being held in Cliffe Castle Park on Saturday, December 3, from 4pm to 6pm, to celebrate the launch of the exhibition.

There will be a light show, accompanied by a festive soundtrack from Haworth Brass Band and Keighley Rock Choir.

The event will also feature a display created by the Hope Project.

Projections of Hope – supported by National Lottery funding via Arts Council England, and by Bradford Council and Bradford 2025 –uses everyday objects to project messages of hope.

Warm refreshments will also be available, raising money for Keighley’s Good Food project.

The glasshouses will then be lit up every night throughout next month.

In a separate initiative, visitors to Cliffe Castle can also learn more about musical stones – and play them.

The rare stones, known as a lithophone, have gone on display in the museum's conservatory.

They were originally donated to the museum in 1906 by the then curator, Henry Phillipson, and have been 'rediscovered' after years in storage.

Musical stones became popular in the 19th century, but few have survived.

To celebrate the new exhibit, a recital and informal talk is being given at the museum on December 3 between 2pm and 3pm.

Four new compositions written especially for the instrument will be played.

And Bobbie Millar of Quarry Arts – and Heather Millard, from Cliffe Castle – will give a short talk about the compositions, the history of musical stones and their significance in the museum collection.

Tea and coffee will be provided.

The event is free to attend and booking isn't necessary, but seating is limited.

Councillor Sarah Ferriby, Bradford Council’s executive member for healthy people and places, says: "This is one of our more unusual and fascinating exhibits – who knew that rocks could be made into instruments which produce such beautiful musical sounds? Come along and find out more about the musical stones and maybe even have a go yourself."
