Numerous additions and restorations have produced a complex, asymmetrical building dating largely from the 16thc. and 19thc. The earliest part is the lower stage of the S tower, dating from the late 12thc. or early 13thc.

Midhurst is not mentioned in 1086.

According to Mee, there is a square Norman font (Mee 1964, 140). However, the present font has an octagonal bowl on an octagonal stem, both decorated with pointed blind arcading.

The ground floor of the tower is dated early 13thc. by Nairn and Pevsner, and is difficult to date precisely.
