S nave, wall, billet string course, detail.

Image of the feature "III. Exterior Features: 3. Exterior Decoration: a. String courses: Nave" at Cambridge.

by Ron Baxter.

Running around the nave at the level of the N and S eaves is a triple billet string course. It continues across the W facade at the same level, where it appears to be original. On the N wall much of the string course is missing at the E end on the nave.
