all of the nave's aisles are the same height as the rest of the church. the walls are plastered and the ceilings flat. the nave arcades have elliptical arches ("as shallow as soane liked them") on thin tuscan columns. the north and south galleries were removed during renovations to the church in 1951, but the west gallery, supported by cast iron columns, remains. in the gallery is the organ, previously in the chancel, now housed in a mahogany case including panels from the 1884 corvette hms "calliope". in the south aisle is an eighteenth-century font.
