A single corbel located on the north-west corner of the nave depicts two human heads. The corbel is fairly weathered, however it is possible to discern that the heads are male with almond-shaped eyes, drilled pupils and prominent chins. The northern face has a thin, closed mouth, whereas its western counterpart has an open mouth.
