(2006). Building stones in the churches and church yards of the Stretton Hills. Proceedings of the Shropshire Geological Society, 11, 2-4. The field excursion which met at Craven Arms on May 15th 2004 focused on churches around the Stretton Hills, since this area is already well known for its complex geology and associated landscape patterns, which might be expected to be reflected in the choice of building stones. Geology and local history have made each of the churches different, but they nevertheless reveal some common trends. Three of them (St Laurence Church Stretton, St James Cardington, and St Peter Rushbury) still have Norman naves built of very locally derived rubble, later enlarged with better quality stone from fewer, specialised quarries. Meanwhile, the church of St Margaret at Acton Scott persevered in its use of the stone won from its own local and unique outcrop of Ordovician limestone. Implications for conservation are discussed and the role of render is considered. 1Bicton, UK. E-mail: [email protected] 1. INTRODUCTION 2.
