In ancient times the chancel was the domain of the priesthood while the nave was for the lay folk. The size of the chancel at Halifax is notable compared with other churches. At one time a grand "rood screen" would have stretched across the chancel arch at Halifax. Today a smaller rood is situated two bays further forward.
In the north and south aisles of the chancel you can see the "commonwealth windows". These windows of plain glass in a beautiful pattern are quite unique and are the result of the puritans dislike of ornamentation. See if you can see the pattern used elsewhere in the church and on this web site.
The chapel in the south east corner of the chancel is dedicated to the Duke of Wellington's Regiment and is also known as the Chapel of the Resurrection. The Regiment is local to Halifax and close to the hearts of many local ex-servicemen. Several of the regiments colours are laid up in this chapel including those from Waterloo and the Crimea.
