The dimensions of the church are as below.
| Length | 146 ft. |
| Width | 53 8 in. |
| Height | 47 10 |
The roof is supported upon wooden ribs, crossed by others of the same materials: the joints are covered by ornamented plates of iron, of very grotesque descriptions: in the nave, the ribs are almost double the distance apart, of those in the chancel: the junction of the roof and walls, in the latter portion of the edifice, are adorned with curious little figures of horses, foxes, &c. &c. interspersed with stars, and many other similar devices.
The entire edifice is supported upon eight columns on either side: three constituting the chance, and the remaining five the nave: the galleries are particularly neat, more especially that appropriated to the organ, the whole of the pewing being covered entirely with green baize. The lancet windows, with which the church was formerly furnished, have almost all been altered for others of a later date, except in the clerestory, where
they retain their original form. The large east window, before mentioned, was formerly adorned with no less than 14 coats of arms richly painted. The roof was put up, at the time that the Norfolks were lords of the borough: in the year 1825, a curious old inscription was discovered upon the summit of the walls, reaching from one end of the church to the other, but it was very remarkable, that the centres of all the letters, (which were about a foot in length) were entirely, and apparently designedly effaced, so that not the slightest meaning could be discovered from it.
In the chancel, is the curious and remarkable effigy of Thomas lord Braose ob. 1396. This noble and ancient family were formerly almost the sole proprietors of the county of Sussex. One of their residences was at Chesworth, an ancient mansion to the
south of the town, which shall afterwards be described; and Bramber Castle also near Steyning, originally appertained to these powerful barons. The head of the figure, “is defended by a basinet, ornamented by a draplet of jewels, his throat by the ample carmail, attached to the helmet as in the time of Edward III. His arms are in plate armour,
and his body in a shortened hauberk, kept from pressing on his chest, by means of the plastron, or breast-plate, within. Over this is the juppon, bearing his coat of arms, viz. seme of cross croslets, a lion rampant crowned. Suspended from his military girdle at his right hip, is his dagger, the sheath of which, is ornamented in an architectural style, and in the same manner at the left, hung his long sword, of which no traces now remain. On his insteps, are large pieces attached to the spur leathers, and terminated by indented edges which conceal the chain mail beneath. His jousting helmet, surmounted by his crest, a demi-lion rampant, issuing from a coronet, is under his head, but greatly mutilated, all below the oscularium, having been destroyed.” [12]
