On the southern side the buildings are larger and less imperfect. Here is the chapel, 'evidently,' says Mr Worth, 'a portion of a larger structure, which has, perhaps, for the most part disappeared....' East of the chapel are the guard-rooms, in a two-storied block of two rooms on each floor. A doorway in the north-eastern corner leads into the porter's lodge, a small room in the gate-tower with 'a loop window in the eastern wall commanding the approach. Above this chamber there is one precisely similar in the upper story (the floor, of course, is gone), and it is noteworthy that this is the only part of the fabric that retains its roof, which is supported by three massive stone ribs.' The barony of Okehampton was one of many grants made by the Conqueror to Baldwin de Brionis, and some generations later it passed by marriage to the Courtenays, in which family it remained until the Marquis of Exeter was attainted and beheaded in 1538. The Castle was among the possessions that Queen Mary restored to the Earl of Devon, and on his death in 1556 his lands were divided amongst his heirs. Okehampton Castle fell to the share of the Mohuns, and in 1628 John Mohun was granted a peerage and took the title of Lord Mohun of Okehampton. The last Lord Mohun died in 1712. To the barony of Okehampton belonged Floyer's Hayes, in the parish of St Thomas the Apostle, near Exeter, and it was held on this curious tenure: 'That if the Courtenays, Earls of Devon, came at any time into Exe Isle, they [the Floyers] were to attend them, decently apparelled with a clean towel on their shoulders, a flagon of wine in one hand and a silver bowl in the other, and offer to serve them with drink.' About thirteen miles south-west of Okehampton, Sydenham stands in a beautiful valley, overshadowed by woods, in which the shining green of the laurels, the darker masses of the rhododendrons' tapering leaves, patches of russet bracken, and feathery light green moss make a feast of colour, even when overhead there is only the bare tracery of twigs and branches. The coverts lie on a hill-side that is steep and fairly high, and at the foot is a rushing stream which is crossed by a bridge exactly opposite the front of the house. The following notes have been most kindly sent me by Mrs. Tremayne:
