Making the entire length of Buildings, inclusive of West Tower, nearly 250 feet.] tower at the west end of the church, which contained the belfry, fell more than a century ago, and, in falling, destroyed the west gable of the church. The buildings of the priory have now been reduced to the nave (Fig. 876), an aisleless structure, 74 feet long by 24 feet wide internally, and to some underground vaulted buildings, which no doubt formerly supported the choir and other erections above. Considerable excavations and investigations have recently been made on the site by the Marquis of Bute, under the careful superintendence of Mr. William Galloway, architect, whom we have to thank for the accompanying Plan (Fig. 877) showing the outline of all that remains of the priory. The explanations attached to the Plan give Mr. Galloway’s views as to the various parts of the edifice. [Illustration: FIG. 878.--Whithorn Priory. Nave, from South-East.] The west tower (1), which fell in the beginning of last century, is now a mere ruin a few feet in height, and the new west wall (2), built in consequence of the destruction of the old gable wall, diminishes the size of the nave. The eastern wall of the nave (Fig. 878) is a post-Reformation erection, evidently added to enable the old nave to be used as a parish church. The cloister (5) lay to the north of the nave, which accounts for there being no windows in the north wall of the latter. Not a vestige now remains of the cloister walk or garth. The chapter house (10), slype (8), and (6) site of domestic buildings extended to the north of the transept. The old foundations and portions of walls remain in connection with the parts tinted black. The parish church (6) is now built on old foundations, with a porch at 7. 9 shows a piece of causeway flooring _in situ_, and 11 is the foundation of a pillar of the chapter house. The crypts (14), which are on a basement floor, show the extent of the choir, and 13 is the crypt or basement of a large building to the south. A considerable portion of the vaulting of these crypts has been preserved. To the east 17 probably indicates the foundations of the lady chapel. To the north of the choir is a detached structure (16), believed, from the remains of feathers, &c. found in it, to have been a larder. The remainder of the ground is entirely covered with graves, so that it was only accidentally that a small portion of the foundation of the south transept (12) was discovered. [Illustration: FIG. 879.--Whithorn Priory. Tomb Recess in Nave.] The nave (see Fig. 878) still retains its ancient side walls, which are probably of the fifteenth century. The south-east doorway is of good form, and the mouldings are also good. “It bears the arms of Alexander Vaus, Bishop from 1426 to 1450.”[168] In the interior (Fig. 879) the north wall [Illustration: FIG. 880.--Whithorn Priory.
