St John's retains many early features. Wall paintings dated at 1280, Norman Pillars and windows, 12th Century transitional arches, 14th Century Parclose screens, a 15th Century Rood screen and remnants of a Rood Loft, with an unusual external entrace built into a turret on the South side. The roof, tower, Oak rood Screen, Pulpit, and the East window are 15th Century, though this window contains some 13th Century glass from the window of the Lady Chapel on the South side.. There are 'Elevation Squints', cut into the Rood Screen. These are very rare, and in Hampshire, unique.
