The SOUTH PORCH was remodelled early in the 19th century to take two Mason memorials.  The inside is now used for the children's Sunday School but is still called the Mason Room. In it there is a fine pair of monuments based on a design by Augustus Pugin. They make lavish use of crocketted pinnacles and embellishment surrounding a simple marble plaque. The Mason arms can be found at the base. The family lived in Necton from the time of Queen Elizabeth 1 until 1930.

The NORTH CHAPEL has the outline of a consecration cross cut into its east wall. This marks the consecration by the Bishop of Norwich in 1326 when Lady Maud, widow of Sir Robert de Tony, gave this chapel. The de Tonys had held the Manor of Necton since 1066. The east window depicts St. Catherine. Also in this chapel will be found a piscina  which was used by the chantry priest for washing the chalice.

The WEST GALLERY was made to fit the new tower in 1865 and is decorated with figures playing musical instruments. Square stones in the nave floor indicate where pillars stood to support the former minstrel's gallery.

DECORATED PERIOD WINDOWS will be found at each end of both north and south aisles. At the east end of the north aisle there is a particularly fine butterfly tracery. The main arcading of the nave is also of the first half of the 14th century. However, the main windows to the north and south were enlarged in the 15th century and are good examples of the Perpendicular Period.

The COMMUNION TABLE is Jacobean and is inscribed 'T.M. 1634' when one of the Mason family donated it. The reredos includes a large painting, a copy of the famous 'The Raising of Lazarus' by Sebastian de Piombo. In a crowded scene it depicts the arrival of Christ and Lazarus struggling with his grave cloths. The reredos is flanged by Commandment Boards.

The FONT was made of Portland stone in 1788, when it cost 9 guineas with a further £4.3.0d to install it. The bowl of the medieval font will be found in the porch.
