C. Blind arcading

The blind arcading running right around the building, with the string course below, itself supported by pilasters, were all incised into the ashlar fabric during or after construction, and together constitute a striking and important feature of St Laurence’s. The fact that this decoration was incised into the stone has suggested to some that it was a late addition to the building, but note the large base stones supporting some pilasters which suggest that the decoration was planned before construction began.
