of the present nave. Parts of the east and west gable walls still remain. At a later period, probably about the middle of the fifteenth century, the church was extended to the south, and was converted into a building with a nave and a north aisle; and again at a still later period, in 1485, the south wall was taken down and a south aisle erected. The north and south aisles correspond in a general way with each other (Fig. 1406), and although the pillars on the north side are round and those on the south side are octagonal, both have very simple caps and bases, all of late form. The arches of the arcade on both sides are round with broad notched splays. There are three clerestory windows on the north side, of a square shape. They formerly had oak lintels on the inside, but these, being decayed, were removed during the restoration, and the stone arches shown in Fig. 1406 were put in. On the south side there are eight clerestory windows, arched throughout. The west tower is not in the centre, but occupies the space between the centre of the nave and the line of the south arcade. It appears to be an addition, but its lower plain vaulted story was probably erected before the addition of 1485, while the upper portion is of later construction. There is an entrance through the tower to the church, which, from the relative positions of the two, is not in the centre. The opening of a flat arched form is shown in Fig. 1406. In 1242 Bishop de Bernham consecrated the Church of St. Vigean. It was again consecrated, along with two altars and the cemetery, in 1485 after the additions were built by Bishop George O’Brien, Bishop of Dromore, in Ireland,[185] acting probably, as Dr. Duke says, for the Bishop of St. Andrews. MONASTERY OF RED OR TRINITY FRIARS, DUNBAR, HADDINGTONSHIRE. This fragment (Fig. 1407) is all that remains of the monastery of the Red Friars at Dunbar. The field in which it stands is still known as the Friars’ Croft. [Illustration: FIG. 1407.--Monastery of Red or Trinity Friars, Dunbar. Plan.] It is generally supposed[186] that this building was originally a belfry of the monastery, and that it was, at a subsequent period, converted into a pigeon house; but it is much more likely that, besides being the belfry, it was also the pigeon house of the monastery from the first. It appears to be still very much in its original state. The walls which support the central portion (Fig. 1408), which rise from arches in the interior (Fig. 1409) and give the structure its belfry-like aspect, are evidently as old as any other part of the structure, and the supporting arches with their corbels are not insertions.
