A general view of the south elevation of the church of St. Nicholas |
The de Warenne
family
owned
quarries
in the Don Gorge - 20 km upstream of Thorne - and
the
dolomitic limestone here has
been used for
finely tooled arcades, arches and doorways in
several churches in the area, which
date
back to at
least 1175.
The south aisle and clerestory |
It is therefore surprising to discover that the walls of the church of St. Nicholas, which have been assigned a date of c.1200, essentially comprise an irregularly coursed jumble of stones that have been quarried from the Quaternary glacial deposits upon which Thorne is set.
A general view of the north aisle and clerestory |
A quick examination of the external walls of the aisles and clerestory shows that the bulk of the stones are large cobbles of Carboniferous sandstone and Permian dolomitic limestone, whose textures vary from flat and very angular to sub-rounded and, according to the British Geological Survey, it is highly probable that these were deposited very near to the front of a melting glacier that flowed from the north-west.
