Possibly the oldest artefact I’ve found in the churches I visit. It is a restored section of flooring recovered from the foundations of a Roman Villa found nearby. The little sign reads
” This remaining fragment of a pavement removed from the foundations of a ROMAN VILLA in the MILL GARTH in 1859 was restored by members of the BRADFORD HISTORICAL AND ANTIQUARIAN SOCIETY in 1929.

I particularly liked the way the peeling paint of the church walls was such a sympathetic foil for the colours in the tesserae/

What a wonderful find.
Almost every church I visit seems to have something ‘unexpected’.
Also, in this church there was a hole cut in the roof with a reflector to through light on a memorial on the wall (there was also a bucket under the hole to catch water!) – I’ve never seen the like in any other church.
