This July, Trinity Community Arts presents Cast Light, a new immersive installation by internationally acclaimed artists Squidsoup, transforming the historic Pump Room at Jacobs Wells Baths into a captivating environment of light, sound and space.

Taking place on 18 and 19 July, alongside Bristol’s annual Harbour Festival, the ticketed experience invites visitors into one of Bristol’s most significant heritage buildings as it undergoes ongoing restoration during the city's annual Harbour Festival. Designed as an audience-led encounter for small groups, Cast Light offers visitors the chance to move freely through an evolving landscape of illuminated forms and spatial sound.

Recognised as pioneers in the fields of light, sound and technology-based art, Squidsoup have created large-scale works experienced by millions of people worldwide, from Burning Man to Alexandra Palace. Their installations have captivated audiences across six continents.

Cast Light is a new artwork comprising an arching arrangement   of towering columns of light accompanied by an expansive soundscape. Installed within the atmospheric surroundings of the Pump Room, the work explores ideas of scale, connection and our relationship with the natural world. The result is an experience that shifts between moments of wonder and quiet contemplation.

“Cast Light began as an exploration of scale, presence and our relationship to the environments we inhabit. The work shifts as people move through it, creating moments that can feel vast and enveloping, but also deeply personal. The title is a nod to the venue - a play on the solidity of the space and its cast iron construction of areas previously never seen before, against the fluidity of light moving through it. The artwork asks you to explore how we appear in the light, and how it transforms the space around us. The Pump Room at Jacobs Wells Baths is a space shaped by human activity and industrial history, and we’re excited to invite audiences into that conversation through light and sound in such a unique heritage site.”

- Squidsoup

The installation is situated in a space that once powered the building itself;. The Pump Room housed the furnace boilers that heated the natural spring waters flowing through Jacobs Wells Baths, making it the operational heart of the Victorian complex.

Visitors are invited to experience both the artwork and the architecture in a setting that encourages personal exploration and reflection.

As part of Jacobs Wells Baths radical citizen-led approach, Trinity Community Arts have created opportunities for local residents to inform its design and development. In recognition of the relationship with its closest members, free tickets for Cast Light will be offered to residents living in neighbouring Brandon House and St Peter’s House.

Cast Light forms part of Trinity’s Art of the Possible series at Jacobs Wells Baths, a programme that opens the site to artists and audiences during its transformation. It is one of a small number of public events taking place ahead of the building’s major reopening in 2029 as a landmark cultural venue and centre for citizen-powered arts in the South West.

The event is proudly presented as part of the Bristol Harbour Festival fringe activity.

Dr Katie McClymont's talk '...and The Spirit Lingered On' explored the idea of community spirituality photo@ Khali Ackford

As momentum builds to save Jacob Wells Baths and return the listed building to community use we are looking back at our archive and sharing our blogs exploring the importance of community spaces. In this blog, first published in 2018 as part of our Heart & Soul heritage project, we reflect on Dr Katie McClymont's  (UWE’s Senior Lecturer in Urban Planning) public talk about municipal spirituality and its social context.

"Before Katie’s talk I did not understand much about the subject but it was an enormously interesting presentation with many specific examples from around Bristol." Audience member

The talk began with an explanation of the meaning of municipal spirituality and the way it occurs in places with civic and spiritual functions. The term is quite broad and can be applied to music venues, libraries, ex-churches, parks, public spaces and community centres. The factor of whether the space is inside or outside is irrelevant, it is the sense of potential for togetherness or inclusivity that is the key. This feeling does not have to respond to an existing religion, it can be responding to something beyond the everyday realm. For example, cemeteries are not necessarily places of religion but to many people have an enormous sense of the spiritual.

As part of her talk, Katie showed examples of church buildings around Bristol that have been re-purposed. They are all buildings that she happened to be passing on her route around the city on a given day, showing how many church buildings are scattered across the city, and the great proportion of them which are being used for something different than the original purpose.

Katie talked about how, through the 1970s and 1980s, there was an exponential rate of church closures. Some of these still have a social function, such as a former church in Easton that is now a centre for supported independence. Currently the Church of England (C of E) closes around 20-25 churches per each year.

A report from the charity Locality documents this selling buildings and what comminities are doing in response to this.

"I found it very interesting to hear that C of E churches are available for sale, listed on the C of E website for the public to peruse. Some of them have descriptions about their future use, for example ‘for continued worship’, ‘community work’ or ‘suitable for a wide range of uses’." Tess Sieling, project intern

Katie cited the strange feeling around seeing churches for sale in such a matter of fact, straightforward way when in fact they are very special buildings. This raised the question: can you put a price on a church? Also, what judgements are being made about the buildings before they are sold? The example of the Bill’s restaurant chain taking over old church buildings was used, as Katie said that in some cases the insides are ripped out but the strong ethos from the church remains. Even in its new function, sometimes a feeling of the old spirit lingers on. Katie is a very passionate advocate about the amazing idea that churches will always be a place to create connections between people and others; people and the past; and people and something bigger than themselves.

Katie made a film about community art spaces around Bristol including Trinity, Jacobs Wells Baths, Barton Hill Settlement and St Mary Redcliffe Church. As well as being a great medium to communicate the joys of community spaces, Katie said that when they were interviewing people from these spaces, after being asked a question, the interviewee would often give a very telling pause before answering which she believes shows the sense of the community space working beyond its physical and material achievements. Sometimes when churches are changed into private use buildings like a holiday home it can feel wrong and perhaps this is due to that change away from its original ethos. Is it because there is a feeling of loss of the shared community space that once was there?

Sometimes when churches are changed into private use buildings like a holiday home it can feel wrong and perhaps this is due to that change away from its original ethos. Is it because there is a feeling of loss of the shared community space that once was there?

Churches have value. They have a common purpose and a built heritage. The debate is what is their value is and when is it lost? If the value is the sense of people coming together and socialising with people they would not normally, then spaces like Trinity offer us examples of activites that do this with great popularity and with no religious aspect.

Churches closing have caused massive losses to local communities. In addition, a lot of us now live in self selective communities, so where do you meet people different from you apart from in a doctor’s waiting room or on a bus?

Katie's talk highlighted the importance of having inclusive places where different people can engage in a meaningful way. Do we define using a church as a multi use community space as adapting the church or losing the church? As an increasing number of us are of no religion, perhaps we are adapting churches to keep them relevant and concerts, gigs and other actitivites offer us that place to congregate in our secular state.

The talk was part of a series exploring the challenges and achievements of transforming and preserving historic buildings and was programmed in collaboration with Bristol's Architecture Centre and the University of West England (UWE).

Our Heart & Soul project celebrated people's major life events at Trinity and ran alongside our current building conservation works. As part of the project we wanted to explore further the challenges and achievements of transforming and preserving historic buildings. The project included a series of talks, inviting both national and international speakers to share their knowledge and experience on the positives and pitfalls of re-imaging historic buildings.

Speaking from an architecture perspective about how a space can be adapted to better serve the community, Trinity Trustee and UWE Senior Lecturer Fidel Meraz delivered the first talk of this programme, and talked about buildings around the world where the function has changed over time, Feb 27 2018...

Most churches were originally built to hold a service once a week - by giving them a second life, the building accommodates for a far larger audience.

What was really compelling about Fidel’s talk was that he spoke in metaphors of the human life, about the way buildings are born as beautiful and well attended sacred buildings, then decline over time until finally they are not active. He used the example that when an elderly person struggles to walk, we give them crutches, and this is also the way he likes elderly buildings to be treated.

An interesting point was made that most churches were originally built to hold a service once a week, therefore in some cases by giving them a second life, the building accommodates for a far larger audience.

When we approach a church we have a predetermined view of what will be inside, Meraz explained, so it is exciting to be surprised by what we find. In Asturias, Spain, the Santa Barbara Church was abandoned and crumbling until the community took action. They raised money and with sponsorship from Red Bull too, it was converted into a vibrantly colourful indoor skate park.

Through time the architectural intention has changed from a place of worship to a space of activity, but the purpose of the building as a space to serve the community remains. He compared the Santa Barbara Church with the Trinity Centre because in both cases what you find on the inside is unexpected and fun.

A lively discussion began after Fidel's talk around Old Market and gentrification. Image credit @Khali Photography

From Fidel’s talk I learned that the world is full amazing ideas of how to reuse spaces. Tess Sieling, project intern

After the talk, Edson Burton invited a discussion between the audience and Meraz, in which the future of the Trinity Centre, Old Market and Bristol were spoken about. Concerns were voiced about the gentrification of Old Market area, which highlights the role the Trinity Centre plays in serving communities.

There is a sense that it is now in a crucial era where the Trinity Centre’s responsibility is to remain accessible to all communities without judgement and, from, Fidel’s talk I learned that the world is full amazing ideas of how to reuse spaces.
