The decoration of the exterior is slight, a dentiled cornice and a graceful foliated frieze extend along the top of the side-walls, which although most plainly built, are far from being severely angular or gaunt and have a quaint and pleasing harmony of line. The west front is so featureless that it scarcely deserves the title of facade. The south wall, which is clearly seen from the road, has a small portal and plain buttresses that slope at the top. The central apse is rectangular and heavy, the little southern apse is short and round, and that of the north is tall and thin as a pepper-box. Behind them rise the pointed roof of the nave and the heavy tower. The whole apse-end is constructed in most picturesque irregularity, and the new red of the roof-tiles and sombre grey of the old stone add greatly to its charm. Unlike many churches of its period Notre-Dame of Vaison is three-aisled. Slender, narrow naves, whose tunnel vaults are not extremely lofty, end in small circular apses. The nave is a short one of three irregular bays, and over the last, which precedes the choir, is the little eight-sided dome, which instead of projecting above the roof is curiously placed a little lower than the tunnel vaulting of the other bays. The High Altar, which originally belonged to an older church, is well placed in the simple choir; for it belongs in style, if not in actual fact, to the first centuries of the Faith; and in the semi-darkness behind the altar, the old episcopal throne still stands against the apse's wall, in memory of the custom of the Church's early days. The low arches of the aisles, the dim lighting of the church, its simple ornaments of classic bands and little capitals, its slight irregularities of form and carvings, make an interior of fine and strong antique simplicity. A little door in the north wall leads to the Cloisters, which are happily in a state of complete restoration, and not as a modern writer has described them, "practically a ruin." The wall which overlooks them has an inscription that adjures the Canons to "bear with patience the north aspect of their cells." The short walks have tunnel vaults with cross-vaults in the corners and in parts of the north aisle. Great piers and small, firm columns support the outer arches; and on the exterior of the Cloister the little arches of the columns are enclosed in a large round arch. Many of the capitals are uncarved, some of the piers have applied columns, but many are ornamented in straight cut lines. On one side, two bays open to the ground, forming an entrance-way into the pretty close, where the bushy tops of a few tall trees cast flickering shadows on the surrounding walls and the little grassy square.
