There are 3 windows in the S aisle with 3 lights each and upper tracery lights on the ground level, with 6 smaller windows with 2 lights each above the nave on the upper level (1 of these over the entrance door). In the N aisle of the nave there are 6 x 2-light windows with upper tracery; the heads of the 3 windows towards the E end contain early 14th c. heraldic glass.
