The North Aisle
In the early 1300s a portion of this aisle was set aside by Ralph de Turvile as a burial place for the Turvile family and other distinguished people it was called the Turvile Chantry. In 1778-9 a wall with a door in it was built across the aisle to divide the chantry off from the rest of the church and the arch between the chancel and the chantry bricked up. This burial place was, at that time called 'Mr Grundy's Aisle' as he had now taken over the rights of the Turviles when he bought New Hall Park and he was Lord of the Manor of Thurlaston. After it was closed off from the rest of the church this part became neglected and was known as 'The Dark Chancel'. In 1832 it was described as being in a 'wretched state' as the Grundy family, who were supposed to keep it in repair in lieu of paying Church rates had failed to do so. In the early 1850s the condition of this are was very bad indeed. It was so dark inside that its contents could only be viewed with lighted candles. It had been used to store coal and several barrow loads of soil were taken away from the decaying remains of many years of Christmas hollies and evergreens which had been thrown away in there. Many monuments were damaged but the large tomb of John and Katherine Turvile was saved and moved, as were some of the other tombs in this area. The end wall (East) was unsafe and had to be demolished and rebuilt a few yards westward. The vestry was added a few years later.
The South Wall
The years 1778-9 witnessed a drastic change in the church. The south aisle was taken down and a new south wall to the Nave was built, with three plain windows in it. The walls of the Nave were lowered and a new slate roof put on.
The interior walls were plastered and a new
main door, five feet wide, was put in, in its present position
in the west wall of the belfry. A new inner door, from the belfry
to the nave, was added and a new floor for the bell-ringers. The
Turvile burial chantry at the east end of the north aisle was
walled up to block it off from the rest of the aisle a small
door allowed access. The chantry was also blocked off from the
chancel by the arches being filled in. A new quarry floor was
laid and a new pulpit, reading desk and pews added.
