The church contains one of the finest collections of memorial brasses in the country.
One brass, in the chancel, commemorates William Lawnder, who was vicar in the early 16th century. The remaining seven, in the north and south aisles and the north chapel, are of Northleach's woolmen.
They are not in their original positions, having been relocated during the re-ordering in the 1960s in the interests of preserving and protecting them from damage.
The brasses are all of exceptional quality. The best and earliest, in the north aisle, is of an unknown woolman and his wife, dated from the style of clothing as ea. 1400. The best known is probably that of John Fortey (d. 1458), located on the line of the north arcade close to the pulpit. Note the concave shaped brackets on the columns on either side of John Fortey's brass which may have supported a canopy over his tomb.
In all the brasses cover a period of some 15O years.
There is a booklet giving details of the memorial brasses available from the church bookstall.
