| A view from the south-west |
Since commencing my investigation of the 70 mediaeval churches in South Yorkshire, at St. Helen’s church in Treeton back in February 2016, by April 2025 I had managed to visit 58 of these, as well as 72 others in the surrounding counties and further afield.
Following on from an afternoon spent in nearby Handsworth, I took advantage of a regular Wednesday morning crafting session to visit the Church of St. Leonard and St. Mary in Armthorpe, dated by Historic England (HE) as “C11, C12 and C15 restored and extended 1885 for patron Lord Auckland of Edenthorpe”.
Entering the churchyard through the lychgate, I noted the north aisle, east windows, porch, weatherboarded bell turret and the rendered exterior, which are all part of the 1885 restoration and presumably account for the church only having Grade II listed status.
After having a very quick look at the irregularly shaped quoins on the south-east corner of the nave, which are made of dolomitic limestone from the Upper Permian Cadeby Formation, I walked quickly around the exterior in an anti-clockwise direction to take a few general record photos.
Passing the vestry (1976), which further detracts from the mediaeval origins of the church, I didn’t examine the limestone used for the C19 window dressings, and assumed that it was a further use of dolomitic limestone, but the honey coloured patina that has developed on the window dressings of the north aisle is more typical of Jurassic oolitic limestones.
I have encountered Ancaster limestone many times, where used in the late Victorian restoration of mediaeval churches built with dolomitic limestone from the Cadeby Formation, even though the latter was still readily available and it is possible that it has been used here.
Moving round to the west end of the nave, the quoins and dressings look like they have been restored with the same limestone used for the C19 work, but it does not have a honey coloured patina. Usually, where Ancaster stone has been used, its distinctive ripple marks, sometimes referred to as ‘streaky bacon’ texture, are clearly seen, but my photo does not show these.
Continuing to the south elevation of the nave, a restored round headed slit window provides evidence of the antiquity of the church and to the right of the porch, the HE description refers to a C15, cusped, square-headed 3-light window flanked by C12 round-headed slit windows., with a square-headed, ogee-traceried, single-light window to their right.
HE further describe the chancel as having a “Small priest’s door with a chamfered, quoined surround and ogee-soffit lintel; on its left a square-headed, ogee-traceried, single-light window; on right a similar window of 2 lights”. Although some of the masonry and tracery have been restored at some time, plenty of the original dolomitic limestone is retained.
Returning to the C19 porch, much of the stonework on its south elevation and in the interior has been badly eroded and has had to be replaced in recent years, with efflorescent salts suggesting a problem with damp. In contrast, the limestone used for the original pilaster on the nave has not been affected to such an extent.
Entering the porch, the round arched south door is dated by Pevsner to c.1200 and it has a very simple form, with no elaborate decoration and very plain capitals to the shafts, which have been replaced quite recently judging by the fresh appearance of the limestone.
