house was constructed on this holm, and that the chapel was built on its ruins. This St. Tredwell is the same as St. Triduana, whose day in the Roman calendar is October 8th. She is not mentioned by Alban Butler. The chapel was much frequented in its day, and many benefits were said to

be obtained from the Saint by her devotees. It is a plain parallelogram ([Fig. 75]), 20 feet 3 inches east and west by 13 feet 10 inches north and south inside, and stands west by south and east by north. There is a narrow doorway near the west end of the south side. Only the lower portions of the walls remain, except at north-west angle, which measures 8 feet high; but here we have, as usual, the unfortunate information that within memory the east gable and south wall were standing. The thickness of the wall on the north is 3 feet 11 inches; east, 4 feet 2 inches; south, 4 feet 3 inches; and west, 4 feet 9 inches. It is stated that there was a window in the east end, and that the doorway was flat headed. No trace of a window remains, and only about 3 feet 6 inches of the door jambs remain. These have a rebate into which a door is fitted, but whether in a wooden frame or not cannot be ascertained. The original floor appears to have been 10 feet above water level.
There is no means of assigning a date to the building, but the difference in the thickness of the walls makes it possible that it has been altered since its first erection. Planned 1870.
