The interior has a notable collection of medieval wall paintings, in particular a Christ of the Trades, dating from c.1460.

[9] Simon Jenkins described the early 20th century restoration of the interior as "masterly" and attributes it to W. D.

[8] It also has some funerary monuments, including one dedicated to John Morgan, and dated 1805, by Tyley of Bristol.

Opinions differ as to its quality; the Cadw record describes it as "good",[1] while Newman considers it "hackneyed.

"[8] Newman takes a more positive view of the church overall, considering it "one of the most interesting in the Usk Valley".
