These two towers are very nearly alike, but the southern, or Harewell, tower is some forty years the earlier of the two, and belongs to the earliest days of the Perpendicular style, Bishop Harewell having died in 1386. The northern tower was built with a sum of money left for the purpose by Bishop Bubwith, who died in 1424, and his arms are carved high up on a buttress upon the north side, those on the west being a modern copy. In one of its two western niches is a figure of the bishop in prayer. Both the towers have two belfry windows on each side, tiny battlements, and a stair-turret on the outer western angle; in both the buttresses are carried up, with but slight reduction in bulk, two-thirds of their height and then finished with small pinnacles. There are, however, certain slight differences between the two towers; their height is not exactly equal, and there are no niches on the earlier one. The south tower contains a peal of eight bells; that on the north is traditionally considered "rotten," but to all appearance it is sound enough. [Illustration: The Central Tower From The South-east.] THE CENTRAL TOWER is Early English to the level of the roof. The two upper stages are Decorated, but there is a curious inter-mixture of styles in them, owing to the repairs that were made after the settlements of 1321. The chapter seemed determined to allow no possibility of another accident, for besides the inverted arches and buttresses of the interior, the original high narrow windows of the upper part of the tower have been fortified by later insertions, by way of bonding and stiffening the structure, which had been so endangered by the sinking of its piers below. There are, however, no signs of any rents in the Decorated part. The tower has square angular turrets, and is divided vertically into three main compartments, each division being marked by a small pinnacle, and the turrets by large compound pinnacles. It is an interesting tower to ascend, the rents in the wall being plainly discernible; and from the summit there is a fine view of Wells and of the valley in which the city stands.
