Nantwich squareSt Mary’s Church in Nantwich (map) was vaulted with a magnificent lierne vault in the mid-fourteenth century. During our visit we scanned the medieval vaults in the chancel, the reconstructed vaults in the crossing as well as the unfinished vaults in the north trasept.

As part of our investigations at Nantwich, we have provided  several options that simulate how the vaults in the north transept may have been completed. The following digital models show these different options.

Option 1: high tierceron apex with steeply a steeply curved transverse ridge rib down to the longitudinal wall arch apex.


Option 2: lower tierceron apex resulting in a shallow-curved transverse ridge rib.


Option 3: tierceron apex level with the longitudinal wall arch apex, resulting in a tunnel vault form.
