The building is in the Decorated style, with columns more slender than those of the Norman period, with pointed arches, and with tracery in to windows. There are six piscinae in the church, indicating that at one time there were six altars.
The stained glass in the east window dates back to 1430, and has an unusual history. Other items of special interest include a small stained glass window above the chancel arch depicting Joseph holding the baby Jesus (an almost unique portrayal), a memorial in the chancel containing a poem written by Sir Walter Raleigh on the eve of his execution, and the memorials to John Kyrle, Man of Ross.
Ross has managed to compile a list of Rectors with pictures going back 100 years.
