Exeter Cathedral Working together to understand, conserve and manage the heritage and mission

Camilla Finlay B Arch (Hons) Dip Arch M Arch Dip Con RIBA AABC Cathedral Architect to Exeter Cathedral Churchcare : Building Performance : 2 October 2014 ‘We are all no more than life tenants of our heritage and we have a moral duty to pass it on in as good a condition as that in which we received it’ William Morris

Today, it is our duty not only to pass our heritage on to future generations in ‘good condition’ but also with a greater understanding of the heritage asset and its specific conservation needs together with a means to maintain the conservation through resources, skills, materials and viable funding streams.

To pass on the tools to maintain the condition Exeter Cathedral Exeter Cathedral exists for the glory of God and as a sign of God’s kingdom in the community. It stands at the crossroads of the sacred and the secular, the spirit and the senses, and expresses its mission through:

• Daily worship and prayer • Welcome and pastoral care • Evangelism and Spiritual Development • Education and learning • Service to the community

Exeter Cathedral - Key Phasing the ‘impressive scale and richness of architectural conception’ Sir Nicholas Pevsner & Bridget Cherry ‘one of the finest interior spaces which has come down to us from the later Middle Ages’ Richard Morris the ‘unforgettable luxuriant palm-branch effect of the vaulting’ Sir Nicholas Pevsner & Bridget Cherry the ‘enchanting realism of the bosses’ Sir Nicholas Pevsner & Bridget Cherry the ‘inexhaustible variation’ of the window tracery Sir Nicholas Pevsner & Bridget Cherry the ‘outstanding figure drawing’ of the early 14th-century glass Sir Nicholas Pevsner & Bridget Cherry ‘unprecedented grandeur’ of the bishop’s throne – ‘the most exquisite piece of woodwork for its date in England and perhaps in Europe.’ Sir Nicholas Pevsner & Bridget Cherry

‘miraculous preservation’ of the earliest series of misericords in Britain Sir Nicholas Pevsner & Bridget Cherry We can add to these the West Front, Image Screen and its fine figures

Exeter Cathedral - 2012 The installation of the 70th Dean of Exeter Cathedral The Very Revd Dr Jonathan Draper and the development of the management and fabric teams at the Cathedral. The delivery of the Third Millennium Campaign, securing the West Front, new Library & Archive, education and music facilities, funding for music, and renewed 2/3rds of the Cathedral Green. A Quinquennial Inspection followed by a new Conservation Management Plan and a detailed assessment of all properties, uses and resources. An Initial benchmarking exercise Quinquennial Inspection Highlighted a need to invest more in the maintenance of the general fabric and the team of masons and conservators who care for structure and artefacts - local areas of severe fabric decay that may be connected to wider environmental impacts - a general lack of understanding as to how the building is performing environmentally and structurally and the impact that this may have on the condition of the fabric - a need for a more ‘inclusive approach’ to projects both in terms of scope and specialists Recommendation - establishing a programme of general monitoring Complexity and weakness in the rainwater disposal systems Limited records of the existing drainage system Defects in the stonework of the building envelope Effectiveness and impact of heating system and services Condition of stained glass and monuments Areas of poor energy conservation Conservation Management Plan Defined the spiritual, historical, aesthetic and community significance of the architecture, collections and setting - limitations of physical assets and endowments as well as the general shortage of roofed space - confirmed the guiding principles for projects: - Understand the place - Significance should guide decisions. - Assess and consult on all proposed interventions thoroughly before deciding whether to undertake them. - Keep thorough records. - Do everything in a logical order. Policy - Understanding comes before work 8

It also has no great endowments and has only a few properties (occupied by clergy or the Cathedral School).

The only significant way in which income can be increased is through work with visitors.

And that any increase in visitors would need to be carefully considered to conserve the architecture and artefacts The Fundamental Problem Working together to establish the wider ‘conservation’ issues and manage the care and development of the Cathedral We have been growing our team of specialists: Cathedral Archaeologist - John Allan Architectural Historian - Dr Jo Cox Conservator - Nick Durnan Structural Engineer - John Mann Environmental Consultant - Tobit Curteis M & E Engineers - Martin and Anne Thomas Interpretation and Exhibition Designers - Event Landscape Architect - Robert Myers and Members of the FAC including Timber Specialist, Hugh Harrison and former Master Mason, Peter Dare Working together to form a common understanding

And with the support of the Friends - establishing a programme of environmental and structural monitoring to inform our approach to all projects at the Cathedral
